Skylight domes periodically need resealing as RV roofing ages and flexes during travel. This butyl-based compound bonds to all roof material types—fibreglass, aluminum, rubber—without damage to transparent polycarbonate domes or their frames. Applied from a 10-ounce tube with superior adhesion properties, the white color matches many RV exterior finishes. Each box contains six tubes, offering enough material for multiple skylights or protective re-applications. The formulation avoids hazardous air pollutant chemicals, and production occurs in the USA.

• White butyl sealant, 10 oz tubes
• Box of 6, suitable for multiple applications
• Safe for polycarbonate skylights, all roof types
