Is JB-Weld safe for interior panels like the spare tire cover? One of the clips broke on the rear hatch piece (spare tire cover) and I was wondering if JB-Weld is safe to use on these vinyl/plastic trim pieces. Thanks!

Thanks......I gave this a try and unfortunately did not have good luck with it (I followed all the instructions, let it cure 24+ hours, and it seems to not bond at all with these plastic trim pieces).
So I guess it comes down to this -- JB-Weld or Regular Epoxy?

Its hard because panels like the rear hatch panels, rocker trims, sail panels, lower console and door panels are made from polypropylene, which is a low energy plastic with horrid adhesion properties.Traditional epoxies( even the plastic weld) and stuff like jb weld just dont stick to it. They may seem to initially stick, but any kind of handling will prove otherwise. There is a special type of epoxy that is made to bond to polypro but it is not exactly cheap. I know 3M makes polypro/polyethelene low energy epoxy, but you have buy the cartridge of adhesive, plus an applicator gun( like a caulk gun but smaller) and the mixing tips to attach to the gun. If you use epoxies alot it may be a good idea to pick some up. Also having the gun and tips will allow use all the industrial grade epoxies, which are substantially better than the junk you get at the auto parts store or local hardware.
In the end, it'd be much cheaper to just replace than panel or source out another clip at the you pick junkyard than sourcing a adhesive that is proper for the job.

I've looked and looked for this panel (even harder for me since I do not have Monsoon). Nobody seems to have what I am looking for (97-99 dark pewter w/o monsoon).
I did find this product online where a user said in a review that it can bond poly plastics (it's called 3M™ Scotch-Weld™ High Performance Industrial Plastic Adhesive 4693H). Was wondering if anyone has experience with this product...

Are you talking about the 2 hook things that hook the spare tire cover into the panel in front of it? I have a couple non-monsoon panels but they are the 97-99 color. 1 is 93-96 graphite and the other is 00-02 ebony. However I will be making a run to the junkyard this week and I know they have a 97 Camaro. I will check and see if it didnt have monsoon. I can grab it for if it doesnt, as long as your not in a hurry.
The epoxy line I was referring to was 3m scotch weld, but not the number you listed. The polypro version is 3M Scotch-Weld DP-8005. It does work well. Loctite I think also makes a epoxy for low energy plastics but I never used that.

Safe, and effective, are two different things. JB-Weld -is-
a two part epoxy formulation. It has very low odor and
definitely does not have the methylene chloride that
most solvent welding adhesives use to make the polymer
relax and link up.
You can find at Wal-Mart, epoxies meant for plastics.
But better is something meant for the job like the
Weldon series (I have a tube of #16 for acrylics, they
offer many). I'd use a backing piece for strength, a
butt joint will have very little.
A can of universal PVC/CPVC/ABS pipe cement from
Home Depot is likely to work well on ABS interior pieces.
Neither of these is "safe" in the sense of an "oops" not
ruining the surface finish. Other than the JB-Weld, which
takes a day to harden up and has negligible solvents.

Found a product at the Home Depot called "Plastics Bonding System" from Loctite. It contains an activator (which cleans and primes the surfaces to be bonded), along with the plastic bonder.
Says it fuses even the hard-to-bond plastics (including the poly plastics).
Giving that a try now....hoping to get the results I'm after (though I have to say the stuff kinda smells like super glue).

I've used JB Weld and it held pretty good. The problem I've had is if you use it sparingly, it will not hold. If you use enough, it will hold pretty well...However, the panel WILL look like you tried to repair it and did a lousy job.
That panel, when removed, has a LOT of flexibility, so I'm curious as to how that product worked.
