Today I used ssr1 on part of my bonneville. I didn't do the whole car, but just some test areas. I'm very impressed. I did everything by hand. I think I like this product better than meguiar's medallion paint cleaner, which is what I usually use the majority of the time. I like the smell better, (mppc has that nasty smell) and I like the fact that ssr1 is a little thicker so it doesn't splatter everywhere. The product went on smooth and disappeared quickly. I didn't notice any marring either from hand use. Way to go Steve.
