Testimonials

"I know Promech was not intended for this use but……….. I’m restoring a ’39 Chevy and has the original chrome bumper. It was really “Tanned” with rust. I sprayed it with Promech and about 15 minutes and a couple of shop rags later, it looks great! Now I don’t have to search for a reproduction bumper.
