But watch out... - Undercoating is great with very thick and stable coating properties. Easy to spray multiple coats and fast drying. However, make sure you purchase disposable sprayer since this stuff is like a spray-bomb. Overspray go's everywhere; on vehicle, you, dogs, cats, ground, house, and down the driveway. Make sure you are 100% covered with disposable clothing, gloves, goggles, head covering, face shield, etc.; you will absolutely be covered in black tar-like substance that is only removable with solvent. Best to just throw away everything involved in spray process. Do not get any of this stuff on exhaust, mufflers, or any other vehicle components that get hot; will produce nasty vapors for months after job. Also, coating is heavy so stay away from vehicle rotational components unless you like vibrations from out of balance driveshafts. Do not make mistake of thinking you can spray coating in any precision manner; cover, mask, and tape areas not to be coated. Procure sprayer with extended nozzle (say 5" or so), this will allow coverage of hard to access areas, and insertion through undercarriage access holes and inner frame areas. Place large cardboard sheet over driveway unless you want large, permanent, sticky black spot. Review: Very good product - Great under coating I been buying this product for a few years .

Do you have to apply it every year?** A: Has lasted for 4 years with only peeling in a few small spots due to poor cleaning prior to applying **Q: If this stuff is sprayed on or near the exhuast or engine, will there be an issue with fire?** A: I don't believe this product is flammable enough to ignite. I've used it to undercoat car frames and the underbody inches from where the exhaust pipes are mounted and have never had an issue... **Q: could I use this on a salt-water boat? Hull and deck?** A: I don't think I would. It worked for under coating several of our Autos. But is somewhat messy while spraying. I think if you put this on a boat, you would probably get it on you every time you got in it. Remember this is tar base. Using it under a vehicle is one thing, but you would be exposed to it on a boat more so. Not saying it won't work. Good luck ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Stuff!

I have a friend who has a garage does inspections an fixs cars an old classics he asked me where I got what's the name of under coating he said it looks like a good product he was going to buy some ### ⭐⭐⭐⭐⭐ Best undercoating on the market *by M***S on June 1, 2021* I've used RusFre undercoating for two decades. It makes a mess, never comes out of clothing, and takes some scrubbing to get it off yourself, but it works great. I run tractor trailers in the northeast, so they're swimming in road salt and corrosive de-icer six months of the year. Rust jacking (rust build up between parts) is a real problem, and can break parts if allowed to fester. I coat the mating surfaces with RusFre any time I replace a part. It eliminates rust jacking virtually 100%, and in the rare cases where it doesn't completely stop it, it slows the process tremendously. It stays on surfaces permanently. A factory-applied frame paint on a truck I bought new was mostly reduced to rust and rot after less than six years. I sandblasted everything, coated all the parts individually with a high quality rust preventative paint, then coated everything again with RusFre. It went through five New England winters after that, with zero visible rust. ## Frequently Bought Together - Automotive Spray-On Rubberized Undercoating Material, 1-Gallon RUS-1020F6 - TCP Global Air Undercoating Spray Gun with Suction Feed Cup - Apply Sprayable Truck Bed Liner Coating, Rubberized Undercoat, Rust Proofing, Chip Guard Paint - Pneumatic Automotive Application Sprayer --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/15833169-automotive-spray-on-rubberized-undercoating-material-1-gallon-rus-1020f1](https://www.desertcart.com.ar/products/15833169-automotive-spray-on-rubberized-undercoating-material-1-gallon-rus-1020f1) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-21*
