Review on Durable and Protective Dicor RP-FCP-1 Fiberglass Roof Coating System - 1 Gallon by Matthew Watkins

I used this on the fiberglass roof of our Class C RV in preparation for a Dicor finish. Firstly, I don't strongly recommend covering your rig with plastic and making sure the roof edge is sealed. This material eats away at the finish on the sides of the rig. The drain found a few small cracks and now I have two streaks that need to be covered and waxed. I literally followed the instructions and everything was perfectly prepared. My shoes even creaked on the prepared surface as mentioned in the video. When you first spray it, it turns amber almost immediately. Oh, and it stinks a lot! When rubbed it becomes very easy to see exactly where you rubbed it as the fiberglass changes color from ash white to a sort of yellow. I am convinced that the preparatory work is the reason that the coating held up perfectly. Just make sure the roof is completely dry, but I'll cover that in the cover review.
