I added this product to the roof of my workshop. It is a metal roof that was showing some signs of wear. I put two coats down with a roller and it was a piece of cake. The product covered easily and looks great. I have noticed a difference of the temperature inside my workshop. I don't run the AC or fans near as much, since I put the coating down. I would defintely recommend this product. The only downfall is you better wear sun glasses when putting it down. I applied it on a sunny day and it is so bright I was seeing spots when I got off the roof.
