Compliments Mr.Gary, I have read many of your answers to RV'ers questions, thank you. You are correct mine is orange peel in appearance, I called Forest River, by the way my RV is a 2007 Flagstaff, it has a TPO roof. I am a newbie to RV's. I thought after watching YouTube video on discerning your rv roof type that i had a EPDM ,it isn't black but it it is not white either on the backside of the membrane, it's a gray fleece, so much for my assumption, its a TPO made by Alpha Systems. I have a dilemma, I recently purchased Dicor Acrylic Coating two step treatment for my "Supposed " EPDM roof, that is TPO. I called Dicor they said it will work on TPO roofs, I also called Alpha Systems and they told me they have not done any testing with Dicor is Acrylic Coating, that I should call Dicor. Alpha did say that there roofs did not need sealing just washed periodically. Alpha also said sealants did not stick well to TPO roofs. I was hoping to seal my roof after repairs, to hopefully add some life to the rubber roof, also cosmetic. So more research before I make a final decision. Has anyone on this Forum put Dicor Acrylic Roof Coating on their TPO roof?
