Well here is what I can tell you, anyone in our club (Central Texas Crossfire) will tell you I am **** about my car, I have had it four years and I challenge anyone to find a new car on a showroom floor that looks as good as mine which by the way has only been in the rain twice so here is the skinny on the protector (and I don't sell or work for them) it has not changed the color of anything I have used it on whether it is outdoor furniture, canvas umbrellas or my cars top, what it does do is make it look new! Good stuff man don't worry just get some....
