The first 3 inches of tape was very good, then after that, the rest of the roll OBVIOUSLY BAD. Masking tape is better. I used it on the exact same type of area on 2 items (cap area on a paintball bunker). The first one was great. I could barely get my fingers off the the tape. THen, 3 inches into the roll, only about 20% of stickiness that the first 3 inches had. FlexSeal cheats on manufacturing. Gives you the real product for your first little strip then cheats on the rest. HORRIBLE.
