Clark squeezed me in a few days after I called, sent before and after pictures, and gave complementary air fresheners for my rear view mirror! Excellent work and awesome customer service!

This is the best uncoating place around. They are very friendly, and they do excellent work. They have you look at the underside with them before and after. The coating is thick and they even do inside the doors. If you don't want your vehicle rusting away, this is the place to go. And they'll do touch-ups every year or 2 as needed for a very fair price.
