Seal-Tite Corner Seal is a game-changing production tape. The sealing side consists of a thick, pressure-sensitive elastomeric seal that sticks and conforms to any smooth or irregular surface, including S-locks. The fleece side provides more superior caulk-cure adhesion than the typical smooth surface of RV exteriors. Corner Seal provides an instant and permanent seal underneath the caulk-and-molding system to provide a double barrier of leak protection. | Dicor Seal-Tite Corner Seal, 2" x 50
