Regular maintenance of your 5th wheel trailer can keep these things from happening. Liquid RV Roof is the ultimate maintenance tool which protects your trailer form UV rays and harsh weather conditions. b) Liquid RV Roof is great for RV repairs of any kind. The application of the Liquid Roof literally saves you thousands of dollars when compared to a new roof. One coat, one time and years and years of worry free maintenance with your RV. The versatility of Liquid Roof is endless from existing EPDM roofs to canvas, fiberglass to pvc. If you have already put a 3rd party coating over your roof or you just don't know what has been applied to your roof over the years there is no need to worry. You simply apply one coat of the ProFlex primer prior to the application of the Liquid Roof. This is part of the reason for its 26 year history in successfully recoating RV’s.
