Urethane Supply Company's Insta-Weld 1 "Thin" instant adhesive should be used when you have a clean break with no gap to fill. It has the consistency of water. To use, spray the broken area with Insta-Weld Activator (sold separately), clamp the parts together, then apply a small amount of Insta-Weld 1. The adhesive will wick into the crack and create and instant repair. Try Insta-Weld on everything. It will either work, or not work, instantly. Does NOT work on olefin based plastics like polyethylene, polypropylene, TPO and TEO. 2 fl. oz. (59 ml) bottle.
