what is panel adhesive?
i believe it is an epoxy version of bondo. how does it differ from JB weld then? and would laying up a layer of regular glass to attach panels be overkill? i see panels come off with a heat gun and a putty knife. i wouldn't think epoxy would release from heat. or did they use a different compound in the 60's and 70's?

When GM discontinued the two part adhesive kits we switched over to a quick set black polyester adhesive for gluing the panels together. It was as close to the correct glue as we could find for front end assembly. However, the cure time was just as close to the GM stuff and this made for a fire drill when putting a front end on. You'd have to have everything exactly where it needed to be or you would end up with a mess.
Now we use SEM 39747 Multi-Purpose panel adhesive which affords us a much longer cure rate with the same bonding properties as the original glue.
Different epoxy glues are made for different items. JB weld wouldn't work well as a panel adhesive.... and just to add a bit more.... even the original panels would separate with a cutting knife and heat gun.

Evercoat VPA is another brand which is mixed with a hardener similar to mixing bondo but when it sets up it is much harder. Also Lords Fusor which is in 2 parts through a gun which I used to bond my donor clip. Setup time was about 40min. The heat gun and putty knife worked very well for me in removing my donor clip. Not an easy job though!

I made a tool years ago for cutting the panels off, if you go to my site and open the pdf link at the bottom you'll see how we made it, there is a good pic in that write up... It's sharp on both sides and zig zag'd.. but heat that bond and it's a awesome tool.. http://repairs.willcoxcorvette.com/1...-installation/

Exactly... The SEM has a longer dry time and I like it.. I've used the Evercoat too... good stuff but I'm old and slow now..

IF 72 still had them, it`s possible somebody removed the rivets from yours, they may not have used the right glue to re-attatch the bracket.
I used a 2 part 3M product... got it at the auto body & paint store. They said it would glue ANYTHING to ANYTHING!

Your right Mike, I probably should have been clearer. Was just trying to explain that VPA gets mixed with hardener similar to how you mix bondo. They are however used for different purposes. Like Mike mentioned bondo is a filler. Might have been little confusing.

Actually the Evercoat VPA is an adhesive for the regular fiberglass cars and NOT for the SMC cars. It IS used as a filler (bondo-like) for both fiberglass and SMC.
Evercoat SMC Panel Adhesive 994 in the bonding adhesive to use on SMC.

the upside-down nose in post 14; that is layed-up glass correct? and what years were smc and what years were standard fiberglass? and i am pretty sure this and all aftermarket pieces will not be SMC. also, bonding glass patch panels to SMC. use the SMC specific stuff?

When I went to the auto paint & body store, and told them what I wanted to do (bond metal to fiberglass) they gave me the 3M 2 part, and said it would work on anything.... layed up, smc, metal, etc. Sorry I don`t have the product number for you, it was quite a while ago.
