Im restoring an old corvette and the rear quarter panel has numerous cracks and a split in it.This damage is from an accident.What I need to know is what 3m product should I use to bond this back together and also bond on a new seam together thanks.

There are numerous bonding agents designed for Corvette use. There are several people on this forum that have extensive Corvette experience one user in particular you should value the opinion of is Shine. I'm sure he will chime in soon.

I did Corvette restorations for about 15 years.

Sounds like a job for fiberglass mat. The bonding agent would be good for gluing a new bonding strip on the back side, but the real strength in glass comes from the fibers. You can't just glue it back together.

Screw some small aluminum straps on the back to align the edges of the cracks. Bevel the edges of the cracks out about 2 inches if possible with a grinder. Brush on some catalyzed polyester resin, then soak some strips of glass mat with resin....put in place....and roll out the bubbles with a ribbed roller you can get from a fiberglass supply house. Build up about 3-4 layers. After it sets, rough sand it to knock off any problems, then skim coat with filler, and after it cures, you are ready to block it flat. It's best to put a heat lamp on it for a few hours first, but not so close that it gets real hot! After that, primer and block like any other repair.

The early Vette glass can be pretty porous, and you can have trouble painting it with old style primers. Shoot it with 2K primer, and you won't have any problems.

thanks jay for the info but myself like you have worked on these for a while what I was asking was what is the 3m part number for the correct bonding adhesive for this type of repair?

3m 1200 I think is what you are asking for. That is best I can remember rite now but if SHINE or some other don't give you the answer I will check tomorrow and see as I have some at the shop.

Epoxy resin ... epoxy resin is something to know about before you start


Resin vs. Epoxy for fiberglass work?


A ONE to ONE epoxy resin like you find at Tap plastics. Different than the resin you build with the first time, it's for making stuff stick the second time ...

No I don't rep Tap
