Correct bonding procedure?
I am still redoing to front end of my wife's 76. The header support beam that is bonded under the body in front of the hood was rusted out. Luckily, a club member with lots of parts corvettes had an excellent one he took out of a 77. What do you guys reccomend for reinstallaition? I have removed all of the old bonding material (looked like black puddy, not resin). The original support beam had seperated from the bottom of the body and it made it look like the headlight buckets were low but it was the body piece between the hood and the headlights that was elevated.
Thanks to all of you guys for all of yourr help!

Seeing how the car is a 76, it is SMC not polyester like older vettes. Lord Fusor makes the best products for this job. I'm not at my shop so I don't have the part numbers with me. Find a autobody supply house and ask for Lord Fusor. They should be able to give you the correct product.

You will find 3 major brands at your paint store; Lord Fusor, SEM, and 3M. The brands are all similar and all will do a good job, one big difference is the price of the applicator gun which is specific to each brand and prices for the guns vary. I have found the SEM to be the least expensive. 3M puts glass particles in their adhesive so that you can't over clamp the parts which is an advantage. When selecting the adhesive you need to know the materials you are bonding together and how much time you will need to do it. Use the gun and the tip that comes with the glue so you get the correct mix ratio, because they are not equal parts.
For SMC/Fiberglass to steel your best choices with at least an hour dry time are:
Fusor #T21
SEM #39747
3M #8115
To glue that reinforcement in place you need plenty of time to align and clamp, getting another pair of hands will be helpful.
Fusor 147 will work but sets up in less than 10 minutes so it would be best for small jobs such as re-bonding a loose section of the header or repairing broken parts. Fusor 100 or 101 is for gluing plastic to plastic not plastic to steel.

I don't like but will spend the $50 for a tube of the epoxy but I am having trouble with the fact that I have to buy a $50 applicator gun. I believe I will only use it for this application. Is there another way?

Fusor and West Systems make a product in a can. Its a 2 part you mix up like bondo, does the same thing. You can put it in a cake decorator or a grout bag to dispence it. I had a Lot to do so I bought the gun and used 3M
