I took off all the rubber roof, the plywood and foil and replaced the plywood and coated the whole roof with rubber then added the cloth and two more coats of rubber looks great and should last a long time good product.

Hello Anthony. After the first coat the temperature was into the 80’s and I was able to work on it comfortably. I did the entire job myself, and I am 62 ½ years old, so most people should be able to do this. Great stuff! I LOVE this stuff, so happy that I got it


I have taken the trailer on a short trip and it rained most of the time. I found no leaks and was very impressed in the ease of this product. Thanks again and I will get you the rest of what I can on Wednesday.
