Yes it will bond any substrate! I used it to rebuild the armrest pad reinforcement in a 99 Blazer which is vinyl and plastic. Also rebuilt a headlight pocket on a Ford 9000 heavy truck. I used the aluminum duct tape to form the pocket and layed saturated mat in place. Once cured (5 minutes maybe) I just pulled the tape and final sanded it. Works great. Once cured it is HARD as a ROCK!!
The glass mat that i mentioned is just that. Same glass mat used with fiberglass resin. The white mat that you can get woven or layered. When you use the glass mat you will need to mix less hardener with the adhesive to slow the cure process enough to saturate the mat thoroughly.
