Crystal Clear Transparent Gorilla Duct Tape features the strength of Gorilla Tape, in a crystal clear tape that does not yellow outdoors. Made with a heavy duty adhesive layer and waterproof backing for extreme durability. This tape is UV and temperature resistant - great for projects and repairs both indoors and out. Crystal Clear Gorilla Duct Tape is best if used between 10F and 120F. To prevent fingerprints, clean your hands prior to using the tape and handle the tape only at edge. Use a straight edge (credit card or similar object), to press out fingerprints. For best results, apply the tape to a clean surface. Airtight patches are best achieved on smooth, dry surfaces with the tape on both sides of the repair (when accessible). Tape size should be larger than the repair area, extending beyond all edges. Rub the entire surface of the tape aggressively, especially the edges. NOTE: Surface patch will gain additional strength with time. Crystal Clear Gorilla Duct Tape works best for patching with a single layer. Not for patching inflatables at seams.
