what do you use to seal a fiberglass roof rv
I personally use Dicor Lap sealants to reseal and maintain RV roofs. These are the same sealants used in the RV industry by many Original Equipment Manufacturers (OEMs), and they are a popular choice for aftermarket use. But itâs important that you use the right sealant for your type of RV roof. Dicor EPDM lap sealant is specially formulated for EPDM roofing and it works on galvanized metal, aluminum and fiberglass roofs. The Dicor Ultra Sealant System is specially formulated for RV TPO roofing. Caution: Whenever you are working on your RV roof exercise caution.
