2-Pack with Nozzles Included. This bundle contains 2 cans of Self-Leveling Lap Sealant, equipped with matching nozzles for convenient, direct use. It is a premium flexible waterproof solution specially designed for RV, camper and trailer roof maintenance. Featuring a self-leveling formula, it smoothly flows into joints and cracks to create a seamless, watertight seal on roof surfaces, vents, pipes and screw heads. UV-stabilized to resist sun damage and discoloration, this non-staining sealant works perfectly with EPDM, TPO, PVC, metal, fiberglass, wood and more. For best performance, apply only on horizontal surfaces within 50°F to 90°F after thorough surface cleaning. It becomes tack-free in 2-4 hours and fully cures in 24-48 hours. This highly flammable product requires proper ventilation and protective gear during use, and keep it away from kids, heat and open flames.
