Gear Aid Seam Grip + SIL Silicone Sealant

GEAR AID Seam Grip SIL Silicone Sealant is a clear, flexible seam sealer made for campers, backpackers, and gear owners who need to waterproof or repair silicone-treated outdoor fabrics. The 1.5 oz tube is designed for silnylon tents, tarps, ultralight shelters, and compatible backpacks.

Once cured, the silicone-rubber formula creates a flexible seal that helps keep moisture from entering through seams, pinholes, and small tears. One tube covers up to 24 feet of seams and cures in approximately 3–6 hours.
