Sam, I'm in the Milwaukee area and CD Products out of Appelton, WI was recommended to me by my cousin who works for a semi truck dealer. Their shop floor had their coating on it for years and years without a problem. I've had one of their coatings down now for over 6 years with zero issues. I had brake fluid leaking on a stored car for about 6 months and it wiped right up, without damaging the coating.
