Resealing your RV's seams and roof on an annual basis can prevent leaks and could prevent damage to your motor home, travel trailer, fifth wheel, or mobile home. Dyco 20/20 is a premium synthetic rubber brush on, solvent-based caulk sealant used exclusively for sealing seams. Apply on fiberglass, aluminum, asphaltic aluminum coatings, urethane foam and metals. Once applied 20/20 Seam Seal gradually forms a flexible water resistant elastometric seal making it ideal for seams around vents, stacks & attached structures such as carports. May be applied at freezing or above. Can be applied with paintbrush or roller.
A gallon will cover about 50-200 square feet of surface depending on thickness applied and smoothness of the seams.
Do not use on EPDM rubber.
