This stuff repairs holes and rips on pretty much anything, including rubber, neoprene, plastic, steel, fiberglass, etc. No messy adhesives – simply peel & stick. Resists UV rays and won’t turn gummy in high heat or on vinyl. Not stiff or brittle in the cold, and has a ‘stretchy’ quality to it. Includes a couple of alcohol prep pads. 3"×5' roll. Type B is for Vinyl. A is for all other materials. Specify type A or Type B.
