woolwax 2 Gallon Undercoating Kit Bundle w/PRO Gun & 2 Wands. Black Color.

UPDATE 1 year- this stuff is great and I highly recommend it! It stopped the rust on my truck, It stayed on and took on a dull black appearance - looks great. I liked it so much, I put it on my 90 F150. Only downside is any time you try to get under the car, you will get this on yourself somewhere. ORIGNIAL - Have rust on my F250 SD. It was either let it go to junk or do something to save it. I purchased this product and applied it about 8 weeks ago. It was easy to apply - follow the directions. Keep it warm and agitate it. I used a small space heater near the 1 gal can. I applied it in December, so it was chilly - about 45°F - Once it was warm and agitated, it poured like maple syrup. The gun worked great. I had some trouble with one of the application hoses falling apart, but was not the end of the world. Black coloring looks great.

Absolutely worth the investment. Make sure to wear clothes you don’t care about when you apply the product, and probably put a tarp down unless you want overspray stains on your driveway. Good for 1-2 winters.

I like this product but not crazy about how well the extended hoses hold up. Both worked themselves off very soon and had a hard time spraying enough product through them both. The regular nozzle works great and looking forward to this product prolonging the life of an older truck!

Works great in the rust belt. Helps protect the frame. Been using for a few years.

The short version; this is a excellent product, if you get it in black it makes your chassis look great! It applies easily with home grade compressors and cleans up easy if you over spray it. I sprayed several trucks and cars and averaged around 3 quarts a truck and 2 a car. At this point I have tried everything else I know if on the market and while there are some good products this is the best in my opinion. Ten out if ten. The pics I uploaded do not do it justice. Every time I look under a chassis I am impressed.

Very easy to apply will wipe off painted surfaces no need for a lot of protection. Get yourself some black clothes if you want to work on your vehicle.

Used on my 2020 trail boss. Plenty enough to cover every square inch of frame and underbody with enough leftover to do another coat. After 4 years the original coating is still on it and not a spot of rust. Every oil change I check the frame front to back and any worn areas get coated using a paper towel. I drive it all winter in S.E. Michigan.

After reading the reviews, directions and watching videos I sprayed this film with confidence that it would dry eventually. 7 days later I drove on wet roads 30 miles it so. When I parked I noticed under rear wheel wells the film had washed off, some of the frame film washed off as well. Seems like a great product but I don’t know how long it takes to dry apparently 7 days isn’t enough!
