I used fiberglass window screen mixed with epoxy.

What kind of epoxy did you use? And not sure what you mean by window screen?

I've also noticed it always seems to crack only where the notches are in the "L" shaped lip the window sweep is attached to.

I've been thinking it would be good to glue or plastic weld those notches so they don't exist on the panel anymore. The 90 degree bend seems to prevent the flexing and cracking.

Do you know the notches / lip that I mean?

Firebird Door Panel Crack – What Years?

Does anyone have any thoughts on a safe product like an epoxy to use on the backside of the door panel to reinforce it and keep from cracking? I am going to pull the staples out this weekend but I thought while I was there I could help it out with some epoxy of some sort. Thank you for any thoughts. Brian

Go back to post #52 in this thread and review that and the subsequent posts. I reiterate, though, if doing it again, I would likely be willing to spend 5-10x the $ I actually did on a better product given the value of pristine panels.

The only addendum I'd add here, is that instead of epoxy use a plastic welder. They are easy to use and the bond is rock solid. Wish I had known about these things earlier, I might have achieved a better result. That said, wrapping GM's bus terminal - bench seat plastic isn't a bad idea either (after you've repaired the crack of course). I'll be doing that to cover up the crack.





If you didn't want to go to the trouble of covering the plastic up, I can see how staining some filler in the crack might give a good result - like this
