The corners where an RV's sidewalls meet the roof cap are some of the most common places for water to find its way in. This kit pairs a 2-inch-wide, high-tack corner seal tape with six tubes of joint-filling sealant so you can build a permanent seal underneath your normal caulk-and-forming system.
Used together, the tape and sealant give corner joints a second, independent layer of leak protection instead of relying on caulk alone.
