San Diego RV Center, serving El Cajon and the greater San Diego area since 1990, applies Rhino roof coating as a spray-applied membrane that bonds to your RV’s existing roof surface. Unlike standard sealants that crack within a year or two, Rhino coating holds up against Southern California’s UV intensity and daily temperature swings for a decade or more without reapplication.
