Rating Can't Go Wrong with KBS
 
You can't go wrong with a KBS product. They are the best in the industry. If your doing some spot spraying, this is the stuff! Bonds well, good adhesion, and easy to use. If your going to the trouble of covering metal with RustSeal, use this to go over it.

Painted my wheel wells with RustSeal and then sprayed a few coats of the Undercoat on and it looks great. From what I can tell, very durable. I recommend to everyone.

Chicago just destroys cars with the winter snow and salt. My twenty year old jeep looks new underneath thanks to KBS spray undercoating. Had I used it on my other beloved cars sooner they'd be in my garage today. Great products can never go wrong, great staff always help somebody and there's no dumb questions, made in America to boot! Thanks KBS.

Rating Undercoat is Great
 
This undercoating is absolutely the best spray can undercoat I have ever used. Sprays very smooth, no spit or sputter, and sprays to the very end of the can. Only wish the cans were a little larger. Alan
