Just One More Coat
One other thing, I wasn't sure about: When we do the "plastic bag test" running our fingers over the paint to feel for bumpiness--contamination,does this block remove this unseen contamination just how clay does or is it most effective for visible stuff like tar, paint, bug guts, etc.?
Bill, Its a replacement for clay, so after you've used it. The surface should be smooth ( baggie trick) as with real clay
