Square Body Interior Door Panel Plastic Material?

[EricU]

What type of plastic are the factory Square Body door panels? Are they made of a TPO (Thermoplastic Olefin)?

If I heat them up, I can move it around pretty well but it I have one panel that is shaped wrong from years of sun and when it cools back down it seems to have a “memory”.

I am doing some experimenting and am having a tough time getting good adhesion to the factory plastics.

I did get a fiberglass repair to hold (for now) but want to make sure that it will hold up.

I am now going to try a different SEM adhesion promotor, the XXX with the flexible epoxy to see if that will work.



Last night I tried CA glue and it didn’t work very well which surprised me as it normally has stuck to everything.
