Star Brite Marine Silicone Sealant | Black, 10.1 oz Cartridge

Star Brite's marine-grade silicone sealant is built to handle the temperature swings and weather exposure that come with life on the road or on the water. Once cured, it forms a tough, rubbery bond that keeps moving with your rig instead of cracking or letting go.

Because it grips so many different surfaces, it works well for general RV upkeep beyond just roof seams — mounting hardware, sealing around fittings, or closing gaps where two different materials meet.

• Bonds to fiberglass, wood, glass, metal, and plastic
• Cures to a flexible, waterproof, airtight seal
• Rated for continuous use from -60°F to +450°F
• Resists UV, weathering, and common chemicals so it won't yellow or break down
• Skins over in about 10 minutes and is tack-free within an hour
• 10.1 oz cartridge fits a standard caulking gun

Keep a tube in the maintenance kit for touch-ups on seams, vents, and hardware mounts whenever a small gap needs closing up fast.
