Just drove a new car or truck home, and winter's coming? A new vehicle is the easiest one to protect, because you can start before the salt and brine do. We offer WoolWax庐 wool-grease undercoating in Clear and Premium Black, and we also offer Dinitrol rust protection.

What protection does a new vehicle already have?
More than people give it credit for. New vehicles leave the factory with real corrosion protection, and it's a valuable starting point. Professional undercoating is something different: an added layer applied to the underside after the vehicle is built, on top of what the factory provides.
If your dealer offers undercoating when you buy, it's worth considering. Judge it the way you'd judge any undercoating, including ours: what's applied, where it goes, and whether it suits your vehicle. Your new vehicle isn't unprotected. The open question is how well that factory protection holds up to years of Cleveland-area salt, brine, and slush, and whether you want an extra layer underneath.
Why owners protect a new vehicle early
If your goal is to keep the vehicle long-term, you should stay one step ahead of the rust. We occasionally see new vehicles with surface rust starting to form just from the trip from the factory to the dealer. That doesn't mean a new vehicle is in trouble. It does mean the underside isn't always untouched on day one.
A new vehicle's first real test here is its first stretch of salted roads. Starting before then is simpler than coating later. Our guide on when to undercoat before a Northeast Ohio winter covers the calendar.
If you've already driven a few winters and see surface rust, you haven't missed the window. See undercoating a vehicle that already has rust. Our wool-grease undercoating will not repair, remove, or reverse rust that's already there. If metal has holes or soft spots, that goes to a mechanic first.
What about the new-car warranty?
Read your warranty and owner's manual before you decide, and ask the dealer or manufacturer in writing how your corrosion or rust-through coverage works and what, if anything, it requires of you. We can't speak for any manufacturer's terms, and we don't make claims about how undercoating does or doesn't affect a warranty.
One general point that helps: the Federal Trade Commission says it's illegal for manufacturers or dealers to claim a warranty is void or to deny coverage "simply because someone other than the dealer did the work." A manufacturer can still deny a specific repair if it can show the work or a part caused the damage. The FTC advises reading your warranty and keeping all service records and receipts. That guidance is about routine maintenance and parts, not undercoating in particular, so treat it as a reason to ask questions and keep paperwork, not as a ruling on any one product.
New trucks and SUVs
Frames, axles, and suspension on trucks and SUVs sit exposed and take the same road spray as everything else. Our pickup truck frame guide covers what to check. Look underneath with a flashlight every so often, and stay out from under the vehicle unless it's properly supported. Never get under a vehicle that's only on a jack.
What our wool-grease undercoating does
Our wool-grease undercoating is non-drying and formulated to help reduce corrosion caused by environmental exposure. It goes on gel-like and firms toward a wax-like feel over several weeks of driving. It stays flexible, so it can be inspected and re-applied. Let your mechanic know the underside is coated when you bring it in for service. No product can fully prevent rust, and we don't promise results.
Clear and Premium Black both provide the same wool-grease corrosion protection. Premium Black is a popular upgrade with a rich black look. Our guide to Clear vs. Black undercoating explains both finishes.
We also offer Dinitrol rust protection, a longer-term option for qualifying new and like-new vehicles. Dinitrol 4010 Clear Coating is a one-step for new and like-new vehicles, including GM trucks with factory coating, and Dinitrol 4941 Black Hard Wax is a one-step for new trucks. We treat both as a 6- to 10-year solution. Dinitrol needs a clean undercarriage and isn't applied over an existing wool-grease, oil, or rubberized coating, so new is the easiest time to choose it. Ask us which option fits.
For our wool-grease undercoating, we recommend having it checked periodically and planning to re-coat about every 2 to 3 years, depending on your driving habits, mileage, weather, and road conditions. Vehicles that see more miles or a lot of road salt and brine may benefit from more frequent applications. That timing is for wool-grease only. Dinitrol is a different product with its own maintenance guidance, so ask us about it separately.
What a mobile undercoating appointment looks like
We come to your home or workplace. For wool-grease, we raise the vehicle on ramps and apply it across the undercarriage. It typically takes about 90 to 120 minutes, depending on the vehicle's size, condition, and prep, and you can drive immediately afterward. Dinitrol takes longer, and we confirm timing when scheduling.
An undercarriage wash beforehand helps, at a car wash or at home with a hose attachment. When needed, we scrape larger areas of loose or flaking rust first, and additional scraping fees may apply depending on condition. We don't do rust restoration, extensive rust removal, or structural repair. Our service-day guide walks through each step.

Frequently asked questions
Should I undercoat a brand-new truck?
Yes, it's worth considering in Northeast Ohio, and a new truck is a straightforward place to start. Factory protection is a valuable start, and undercoating adds another layer before the salt and brine arrive.
Does undercoating void a new-car warranty?
We can't answer that for any manufacturer, and we don't make claims either way. Read your warranty and owner's manual, ask the manufacturer or dealer in writing, and keep your service records and receipts.
How soon after buying should I undercoat it?
There's no fixed date. Aim to have it done before regular salt and brine season, and don't wait for rust to show up.
