HARD-ON by woolwax™ 5 Gallon Pail Auto Truck Undercoating Permanent Black Water Based Corrosion Inhibitor Coating One Time Application Non-Rubber Stops Rust Chip Guard Sound Deadener Solvent Free

I've done 2 vehicles , one infinity and one rv so far and I am quite impressed. The color is bluish but does dry to 100 percent flat black as advertised. I used the wool wax pro gun and had 0 issues spraying. You do have to clean more frequently than woolwax creep n crawl but no more often than using latex paint.The bluish tint helps to tell when it is dry and did take 72 hours to turn full black, the creases in the one picture are after 48 hours and are still faintly blue but hard to the touch.Dry, well it's like armor. Together with the creep n crawl you can make your or your customers vehicle laugh at the winter and salt. The low odor and no overspray also contribute to how good of a product it is, some hard coatings are just unbearable to spray in my small garage. Hard on rocks!

I didn’t have to apply it; so 5 stars. It a pain to apply, but so worth the results. Solid protection and performance. Lots great and cleans easily. Do your vehicle a favor and put this on it.
