Gluing Quarter Panels On vs. Welding

I decided to use adhesive for a cowl repair.
That will be my first, and probably only use of adhesive.

I contacted the Mfg. for suggestions since this is a non-standard repair.
In other words it's not something for which there are any manufacturer's guidelines.
My concern was that although they are weld thorough, I don't have a spot welder. I only have MIG and TIG.
I figured they don't build cars, but they know the heat characteristics of their products.
They were nice enough to give me suggestions for this repair only and for the specific antique car that I am doing only.
(That's understandable from a legal standpoint)


They said:
1. I was correct in my assumption that spot welding would require a very expensive machine.
2.I could MIG plug weld if I kept one inch away from the adhesive.
(I won't be able to do that with the narrow flange on the cowl.)
3. Using just the adhesive would be fine.

In answer to your specific question, I would not just glue a quarter on an A body.
I had read that the hobby level spot welders were questionable with weld through adhesives.
So the reply I got tends to confirm that.

If you don't have a welder or don't want to do that there is something call rivet bonding.
Same thing, only different. May or may not be what you want.
I'm sure you know that the C pillar and A pillar are flex points.
Lead worked good there. So does solid welding.

By the way, but from what I can find out there is a difference between MIG and TIG.
MIG can change the metal structure in such a way that it weakens the surrounding metal and may not be the ideal choice for structural repairs. But it is what it is.
Your research/opinions may vary.
Perhaps some certified or certifiable welders can light that one up.
