Ziebart: Rust Protection Warranty, Yearly Inspection and Who Owns It

If you searched for Ziebart, you are probably weighing its rustproofing, pricing paint film or tint, or buying a used car whose paperwork mentions a Ziebart warranty. What matters is what each service is, what the warranty promises, what keeps it alive, and whether it passes to you. On 16 October 2026 we read Ziebart’s warranty program page, its FAQ, its help-center page on rust protection and undercoating, its service, dealer, fleet, history, corporate, franchise and terms pages, eight of its own posts, and one federal court judgment. This site has no commercial relationship with Ziebart, any Ziebart store or any car dealer.

What Ziebart sells, in its own words

Ziebart describes itself on its History page as “the worldwide leader in detailing, films and structural protection services.” Its About page lists twelve lines of business, from detailing to auto glass and lease turn-in work. The protection products carry the warranties:

• Rust protection. A coating “designed to penetrate all upper body seams, joints and areas most vulnerable to corrosion such as doors, hood, and trunk,” in the help center’s words; it includes undercoating.
• Undercoating. An underbody sealant, sold alone or with rust protection. Ziebart says it uses “an asphalt-based undercoating”; a wax-based one is “Available at select locations.”
• Sound deadener. “Thicker than undercoating,” an underbody layer meant to cut road noise.
• Rust Eliminator. For older cars: a product “which converts existing rust to an inert state,” applied before sealing.
• Z-Gloss ceramic coating and Diamond Gloss. Two paint coatings. Z-Gloss is the ceramic one, described in a 2019 post as “a three-layer coating”; Diamond Gloss is “resin-based.”
• Z-Shield paint protection film. A clear film against “stone chips, car wash scratches, bug splats, acid rain and bird droppings,” sold in three packages of panels.
• Window tint. Three film series (dyed, metalized and nano-ceramic). The help center adds that “Available film series varies by location.”

Which rust treatments help in general is covered in our guide to protecting a car from rust. This page sticks to what Ziebart says about its own products and paperwork.

The warranty page puts one footnote under its whole program: “*Limited Warranty. See Store for Details.” The rest of this page is about what that means in practice.

Rust protection and undercoating: how Ziebart applies them

Ziebart’s rust protection is not only a spray under the car. The FAQ says it covers “the hood, all body panels and the trunk,” with “a thick, abrasive-resistant undercoating solution” on the underside. To reach the inside of closed panels, the help center is direct: “The Ziebart process does require the opening of access holes in some body panels.” The access is needed, it says, “to assure proper coating of critical welds and hidden areas.” A 2015 post, warning against doing it yourself, asks where to “drill the holes in your rocker panels” and how to “plug those holes when you’re done.”

Small plugs in door jambs or rocker panels can be a sign that a car was rustproofed this way. If you are paying, Ziebart’s August 2025 post says it offers “the opportunity to inspect the work”; take it, and ask where the holes are.

Underneath, Ziebart says its technicians treat the exposed areas “while carefully avoiding areas like the brakes, and the exhaust and drive shafts.” A 2015 post adds a warning that applies to any spray job: some parts “(Sensors, electronics, etc.)” may be damaged if they are sprayed.

Ziebart’s aftercare advice for undercoating, in its words:

• The coating will “skin over” in a few hours and be “dry to the touch in about 24 hours.”
• Keep the car out of a garage, “especially if your garage is attached to your home,” for “the first 1 to 2 nights,” because the solvents give off an odor as they dry.
• Avoid automatic car washes “until the undercoating material is completely dry. This could take up to 7 days.”

The wax-based undercoating, Ziebart says, is “safe for electric vehicles” and comes with “a nationwide warranty” and an annual maintenance program. Its May 2025 post reports salt-spray tests against “two of the industry’s leading competitor products”: the coating “originally passed the test at the standard 1200 hours,” and Ziebart says the test ran to 2700 hours with “a score of 9 (representing up to 0.03% corrosion found),” against a score of 6 for the next competitor. The post names no laboratory, links no report and does not name the competitors; read the figures as Ziebart’s claims.

For a car that already has rust, Ziebart draws a line. A 2018 post says that for rust protection, “if you have a hole in your door or side panel that was brought on from rust, or, the paint is starting to bubble, it’s already too late.” No coating restores metal that is gone. Our rust guide covers when rust is worth repairing.

The rust warranty: what is printed, and what is left to the store

Ziebart publishes no rust warranty document. What it publishes are descriptions, spread across pages written years apart:

• The name. The Rust Protection page and the September 2026 post call it “a national limited full-repair warranty.” The services page says the car “will be completely protected from rust with a full repair warranty to support it.”
• What it covers. The FAQ: “Our rust warranty includes unlimited mileage and coverage against road salt, sand, and (normal) road debris.”
• Which cars get it. The help center: “Any vehicle that is less than 3 years old or 36,000 miles will receive the Rust Protection warranty.” That is the wording; it does not say whether both limits must be met. A 2015 post said Ziebart warranted rust protection “on new, personal-use vehicles for 10 years” and had “warranties for used and commercial vehicles.” No current page states a length.
• How to keep it. “To keep your warranty, you must have your vehicle inspected within 60 days (+/-) of the anniversary of the original application.” By our arithmetic that is a window of about 120 days each year, centered on the anniversary. Ziebart says it mails a reminder card around that date.
• Where to read your terms. The FAQ: “Warranties are specific to the Ziebart service in terms of what is covered, length of warranty, transferability, etc.” Details are in “your original contract,” or from your store or Ziebart’s customer service.

What the yearly visit involves, from the FAQ: the underside is power washed, worn undercoating is touched up, “access plugs are removed and each panel is inspected,” and Ziebart’s Z-Gard is sprayed on the door seams. Ziebart’s help center adds the money side: “Although there is no charge for reprocessing, the owners labor rate will be charged for preparation and cleaning.” A store “may offer you a guaranteed yearly pre-cleaning fee,” but “the guaranteed fee is for that location only. Other Ziebart locations are not obligated to honor those guaranteed prices.” Ziebart prints no figure for that fee.

If rust appears, the FAQ says to bring it to your Ziebart store “as soon as possible,” and that “Your dealer will determine if the rust is in an area that has already been treated.” Ziebart calls its stores dealers; the store, not head office, makes that first call.

What can end the warranty? Nothing we read lists exclusions. The only condition Ziebart prints is the yearly inspection, so treat a missed inspection as the main risk, and ask for the store’s written terms on anything else (accident repairs, rust that was there before treatment, a car that moves to another state).

Ziebart’s rust warranty next to a carmaker’s

Ziebart sells its warranty partly against the one that comes with a new car. Its help center says: “many OEM warranties exclude corrosion that is the result of contact with road salt or other chemicals. Ziebart’s warranty has no such exclusions.” Its May 2025 post puts it shorter: “Most factory warranties do not cover rust caused by road salt, Ziebart does.” A 2015 post said “a typical OEM anti-corrosion warranty lasts about five years,” and the September 2026 post says “Your factory warranty already covers perforation for 5 to 12 years anyway.”

Those are Ziebart’s descriptions of other companies’ documents. Here is what three carmakers’ booklets print, as this site transcribed them for its warranty pages, beside Ziebart’s own wording:

The carmaker coverage is for rust that goes all the way through a panel; our pages on the Honda, Nissan and Subaru warranties quote each booklet. Ziebart’s wording (“full-repair,” road salt and sand) sounds broader, but without the contract you cannot see what it excludes, and it comes with the yearly visit.

Will Ziebart void the factory warranty? Ziebart’s FAQ answers flatly: “No. Our process will NOT void your manufacturer’s warranty.” Its help center is more careful: “Our coatings will not typically void your new car (factory) warranty.” The document that decides is your carmaker’s warranty booklet, not Ziebart’s FAQ; read what it says about aftermarket products before you book.

Paint coating, paint film and window tint: the warranty wording

Z-Gloss ceramic coating. The Z-Gloss page says it “comes with an industry-leading ten-year limited warranty. We’ll inspect it once a year.” The help center says “a 10-year warranty and a rejuvenator service,” and invites you back each year to “Rejuvenate your protection at a discounted price.” Neither says whether the yearly visit is a condition of the warranty, as it is for rust protection, or what “limited” excludes. Ziebart says the finish resists “light scratches,” among other things; that is not a promise against deeper ones.

Z-Shield paint protection film. The film page promises: “No staining, no fading - guaranteed!” and calls the warranty “industry-leading” without giving a length. The 2020 warranty post says the same: “We guarantee no staining or fading.” Expect some haze or “moisture bubbles for up to ten days after installation,” the help center says; wait “at least 3 days” to wash and keep a pressure washer away from the film’s edges.

Window tint and other films. The warranty page: tint and other films “come with a nationwide replacement warranty. We will replace any tint or film that shows signs of peeling, bubbling, or discoloration - no questions asked.” The 2020 post adds the length: “For as long as you own the vehicle.” That ties it to you, not the car, the same way Gerber words its repair guarantee (see what happens to that one when you sell). A used-car buyer should not assume the tint warranty came with the car.

Care after tinting depends on which Ziebart page you read. The FAQ says windows “should not be rolled down or cleaned for 3 days.” The help center says not to roll them down for three days and “Please do not clean inside your windows for 10 days.” Follow the longer one. Ziebart’s tint pages do not discuss state limits on how dark tint can be; check your state’s rule before you choose a shade.

Diamond Gloss and interior products. We found no warranty wording for Diamond Gloss, only an annual renewal “at a discounted price.” Germ Defender is described as working “for up to 90 days.” For a lease, Ziebart’s lease page pitches film on “bumpers, fenders, door edges and hood” and says damage a standard credit card can cover “could be considered normal wear and tear (although this is at the discretion of the dealership).” Your lease contract’s wear standard is what counts; see how lease wear is judged.

Buying a used car with a Ziebart warranty: how to check it

A car that was rustproofed and a car with a Ziebart warranty still running are not the same thing, and only paperwork shows the second. Start with the FAQ’s one sentence on transfer: “our warranty is transferable on new vehicle applications.” Read as written, that covers rust protection applied when the car was new; it says nothing about a treatment applied to a used car. Ziebart does not say whether a transfer needs a form, a fee or an inspection.

Then remember who holds the records. Ziebart’s help center says each store’s owner “is responsible for the workmanship from that location, warranties issued, fees charged, and for the maintenance of customer records,” and that you may “have inspections performed at any authorized Ziebart service center.” The selling store has the file; any authorized store can inspect.

Two other sources can help. Ziebart’s May 2025 post lists “Now Reported to CARFAX” among the benefits of its wax-based undercoating, so a recent Ziebart visit may show on a history report; an older one, or one at a store that does not report, may not, which is why a report is only as complete as what gets reported. And a mechanic can look underneath: our pre-purchase inspection guide explains why fresh, thick undercoating on an older car deserves a closer look rather than reassurance.

If the car was treated after it was sold new, or the inspections stopped, Ziebart’s warranty page says some owners keep coming back anyway: “Even if the warranty period is up, our customers still bring their vehicle in so we can inspect and reapply our services as needed.” That is paid upkeep, not a warranty.

Ziebart at the dealership, and on ex-fleet cars

You can meet Ziebart without visiting a Ziebart store. Its dealer page is written for dealerships, under the headline “Turn Vehicle Protection into a Revenue Boosting Profit Center.” It says: “Since 1959, Ziebart has been partnering with car dealers to offer high quality, exclusive products and services at affordable and anchored prices. With more than 1,000 active car dealer partners.”

The newest program changes who does the work. The Gold Shield Program “helps dealerships add trusted in-house protection products, strengthen F&I, and grow revenue without major upfront investment,” and “Your existing prep staff will receive hands-on training from the experts at Ziebart to deliver protection services professionally and efficiently.” In other words, at a Gold Shield dealer the coating may be applied by the dealer’s own staff, not a Ziebart store. Ziebart’s February 2026 post says it will also “introduce a new in-house car dealer program.” None of these pages says whose warranty applies to dealer-applied products, or who does the yearly inspection.

If a Ziebart package appears on your buyer’s order, it is an add-on with a price you can question; our guide to dealer add-on lines explains where these sit. Before you agree, ask three things in writing: who applied it, which warranty comes with it, and where the yearly inspection happens. Dent Wizard’s dealer program raises the same question for dent repair; see how that one works. Some states also require an advertised car price to include charges such as undercoating or rustproofing; our out-the-door price guide quotes the rules.

Fleet vehicles are the other route. Ziebart’s fleet page says its services can mean “increased resale value at auction,” and its fleet brochure says fleet rust protection is “Backed by up to a 10 year warranty*,” with the footnote “*See dealer for details,” and that the yearly respray “may be performed at your facility by an authorized Ziebart technician.” If you buy an ex-fleet car with a Ziebart history, its terms were set by the fleet’s own agreement, which you are unlikely to see; ask the seller for it.

Who owns Ziebart, and who owns your store

The company is Ziebart International Corporation of Troy, Michigan. Its corporate-information page says simply: “Ownership: Privately owned corporation.” Its History page traces the line: the first rustproofing shop opened in Detroit in 1959, the first franchise was sold in 1962 in Perrysburg, Ohio, the businesses merged into Ziebart International Corporation in 1973, and in 1994 the company “is bought by its employees through an Employee Stock Ownership Plan (ESOP).” A March 8, 2022 release says Thomas E. Wolfe, “After 28 years at the helm,” handed the company to “his son and successor, Thomas A. Wolfe,” who became President and Chief Executive Officer; the father stayed on as chairman. A February 2026 post still names Thomas A. Wolfe as chief executive. Nothing we read says whether the employee plan still owns the company, 32 years on by our arithmetic.

Your local store is another matter. Ziebart’s help center says “Most Ziebart facilities are owned and operated by an independent businessperson licensed to use our trademark,” responsible for “all aspects of his business including the workmanship from that facility, warranties issued, fees charged.” Its corporate page counts “11 company owned stores in Illinois, Michigan, Minnesota, Ohio, Pennsylvania and Poland.” The rest, by Ziebart’s description, are run by independent licensees.

Ziebart’s franchise pages show how that relationship works: a franchise fee of $45,000, “Weekly Royalties 8%” (the pricing page shows a range, “8%-5%”), an initial term of “ten years,” and an “eight-week training program.” The franchise page claims “26 Years Avg. Length of Ownership.” The full Franchise Disclosure Document is sent only to people who submit their details, so we have not read it. For you, the practical point is the help center’s: fees “can vary from store to store, state to state,” and the store you buy from issues your warranty. A company-run chain works differently; compare Pep Boys’ printed repair warranty. The same franchise question comes up at AAMCO.

How many Ziebart stores there are

Ziebart’s pages give several answers, and they do not match:

Ziebart does not define a “service center”; the figure is larger than every count of locations. For the United States, the most concrete number we could find is in its sitemap, which lists 86 distinct location pages (89 entries, three of them repeated). One of the 86 is in Puerto Rico; the others are in 20 states. Michigan and Ohio have 15 each, New York 13 and Indiana 12: 55 of the 86, by our arithmetic, in four Great Lakes states. Illinois and Pennsylvania have five each, Wisconsin four, Minnesota three, West Virginia two, and twelve states and territories one each, from Florida to Hawaii. We opened one location page and it was live; we did not check the rest, so these are pages listed, not stores confirmed open. The franchise page’s “nearly 100” is 14 more than the pages listed.

Canada is handled elsewhere: the store finder says “For locations in Canada, please visit www.uniglassplus.com.” Abroad, Ziebart sells country rights as master franchises, and its International Locations page lists 36 names, the USA, Canada, Puerto Rico and Saipan among them. The February 2026 post reports three new franchise agreements and four new locations in 2025.

Courts, regulators and the website’s terms

Web searches on 16 October 2026 of the FTC’s site and state attorney-general releases found no enforcement action against Ziebart International Corporation. The BBB’s site blocked our request, so no rating is reported here.

The one court record we read shows the franchise system from the inside. In Ziebart International Corporation v. Waggoner Enterprises, Inc. (U.S. District Court, Eastern District of Michigan, Case No. 2:12-cv-12001), the court entered a default judgment and permanent injunction on July 12, 2012, after the defendants “failed to plead or otherwise defend in this case.” It declared the Ziebart license agreement dated July 15, 1997 “terminated, effective September 1, 2011,” barred the former licensee from using the Ziebart name for its vehicle care business in St. Cloud, Minnesota, and ordered it to remove from the internet anything suggesting it “ever had any relationship with Ziebart.” A default judgment means the other side did not contest the case; it is not a finding after a trial. The lesson for a car owner is narrow: a shop can stop being a Ziebart. If your paperwork names a store, check that it is still on Ziebart’s store finder before you rely on it for a yearly inspection.

Ziebart’s Terms and Conditions govern the website, not your service. They say the site “is provided solely for the use of current and future customers and franchisees of Ziebart,” choose Michigan law and the courts of Oakland County, Michigan, for disputes about the site, and allow Ziebart to change “the products, programs, services, or prices (if any) described in this website at any time without notice.” The document that binds you and the store is the contract you sign there.

Where Ziebart’s own pages disagree, and what to ask

We found ten places where Ziebart’s documents do not line up:

• Size. 1,300 service centers in 37 countries, or “over 1,200” in 36, both on the History page (table above).
• U.S. stores. “Nearly 100,” against 86 location pages in the sitemap.
• Sales. “$194 million worldwide dealer sales” (corporate page) or “$170 million” (History page, in a paragraph from about 2019 by our arithmetic). Neither is dated.
• Age. “65 years” on the About and Rust Protection pages, 67 years in the September 2026 post and on the franchise page. 2026 less 1959 is 67.
• The factory warranty. The FAQ says Ziebart will “NOT void” it; the help center says “not typically.”
• Paid yearly inspections. The September 2026 post faults dealer rust warranties whose “‘Lifetime’ coverage usually requires paid annual inspections.” Ziebart’s own requires a yearly inspection with labor charged for preparation and cleaning.
• Where products are made. “Almost all” made in the United States (FAQ), or “All Ziebart products and services are made and sourced in the United States” (February 2026 post).
• Washing after Diamond Gloss. “The first 24 hours” (FAQ) or “3 days” (help center).
• Cleaning tinted windows. 3 days (FAQ) or 10 days for the inside (help center).
• The yearly visit. The FAQ includes removing “access plugs” and checking the hood and trunk seams; the Rust Protection page’s version leaves both out.

None of these changes what to do: get the store’s written terms. Ask what the warranty covers and excludes, how long it runs, what the yearly visit costs, whether and how it transfers, and, if a dealer sold it, who applied the product.

Common questions

Is Ziebart rust protection worth it?

We do not rate it. The answer depends on where the car lives, how long you keep it and whether you will make the yearly inspection that keeps the warranty alive. Ziebart’s claims about its coatings are its own; its 2025 test figures cite no named laboratory. Three carmakers’ booklets this site has read already cover rust-through for five years with no mileage limit. Our rust guide explains what any treatment can and cannot do.

How much does Ziebart cost?

Ziebart prints no prices. Its FAQ says your local store will “give you an accurate quote specifically for your vehicle,” and its help center says independent owners’ fees “can vary from store to store, state to state.” For rust protection, ask for the yearly preparation and cleaning charge too, since that is part of the cost of keeping the warranty.

Is the Ziebart warranty transferable?

For rust protection, the FAQ says the warranty “is transferable on new vehicle applications.” Tint and film are warranted “For as long as you own the vehicle,” per Ziebart’s 2020 post. Ziebart does not publish the transfer steps; ask the store that issued the warranty.

What if I miss the yearly Ziebart inspection?

The help center says the inspection must be done “every year, +/- 60 days of your anniversary date, to maintain your warranty.” It does not say what happens after a miss. Assume the warranty may have lapsed and ask the store in writing.

Does Ziebart void a new car’s warranty?

Ziebart’s FAQ says “No. Our process will NOT void your manufacturer’s warranty,” while its help center says its coatings “will not typically void” it. Your carmaker’s warranty booklet is the document that decides.

Who owns Ziebart?

Ziebart International Corporation, a “Privately owned corporation” in Troy, Michigan, bought by its employees through an ESOP in 1994 and run since 2022 by Thomas A. Wolfe. Most stores belong to independent franchise owners; Ziebart lists 11 company-owned stores.
