Re: UV problem - the real answer

Larry Severson

The dry film thickness of the paint that did not allow UV to discolor the epoxy was 5 mils (0.005 inches) thick. We need to do a more controlled test to make sure of this number, but it looks like if you have 5 mils of white paint over the epoxy composite you will be safe for many years. If you put a black tint in it it is even better, and a red tint works well also.

So the answer is .005 inch is the answer, not 5mm. I heard mils as mm, but I heard wrong.
