Hey everybody, I'm taking my interior out so I can rewire the car. When I put it back in I want it to be tight enough not to rattle/fall apart under the force of the 800W (RMS) stereo I'm about to put in there. The fiberglass is old obviously, and it's really dried out and brittle. Is there something I can do to it (apply to it) to make it a little tougher? I'm afraid it's going to literally rattle apart if I put it back like it is now. There are a lot of places where it is cracked as well, but I'm thinking some fiberglass resin should take care of those spots.
