Has anyone ever done this procedure using Panel Adhesive instead welding the pieces to the longitudinaL?
Panel adhesive is used extensively on new cars, instead of welding.

Sorry, the context of this question got dropped by our system. What was it you were trying to do?

Sounds like he is talking about doing the reinforcement deal, but I think you would probably want to weld that stuff in. In a new car, you are putting two pristine parts together. If you are putting the reinforcement kit in, you are putting a pristine part on a 40 year old part.

I suppose that you could use adhesive, if you were absolutely confident that you could get the parts in good condition to bond. I'm guessing that means surgically clean, with no paint and no hint of rust or seam sealer or anything else, except perhaps an adhesive-compatible primer...

You'd probably want to talk with the people who make the adhesive about what it requires to get a good structural bond. If they say that it'll work on 40-year-old steel of uncertain alloy with some imperfections, then cool. If not, welding is a known solution to the problem.

I used panel adhesive to do floor repairs in my 914. You have to have the surfaces very clean and I had to have some significant weight on the patch to get it to bond.

Even with that, I had several patches pop loose, at least partially. So I would recommend cutting out the rot and welding in new metal. Anything less is just pushing the can down the road to a place where it will be more expensive.

new cars are designed to make it work. correct tolerances, ect. Our old cars need metal welded to metal.

My company is a supplier of structural assemblies for the C7 corvette. There is extensive use of structural adhesives in our assemblies, used in conjunction with spot / mig / laser welding in these joints. To me, I would consider it along with welding, but not as a replacement. BTW, the stuff we use claims each 10mm in bead length is equal in strenght to one spot weld.

Very true,I still think the OP will need some sort of mechanical fastening to hold the panels in place to get the correct bond or some sort of complex bracing during the curing of the adhesive,it's in the too hard box really:rolleyes:.
