That's not the only issue.
In the 80's, conversion van companies tried spray foam inside the doors on their vans.
The practice was discontinued after a year or so, when it was discovered the foam caused the doors to rot out.
After- Market Body Panels..... Any BODY men there?

interesting... now that i think about it, i could see the slick smooth panels not bonding with the spray foam. and allowing some moisture / condensation in between the to. with a little bit of air mixed in, causing some rust to happen.

Man I purchased a 1973 GMC Jimmy brand new so this brings back some memories.That thing started to rust in two years.I rebuilt it twice and finally sold it about 1982 with about 90, 000 miles.It constantly got 11.5 mpg with the 350 chevy and full time 4wd.Hard to believe there are still some around.
I have used aftermarket body parts for many years and have never had a problem with buckling panels. I also have never heard of that brand but I think most parts are very similar from co. to co. and may be manufactured by only a few manufactures. Any way without seeing what you have I would suggest coating the inside of the panels with liquid truck bed liner and call it a day or get new panels.
Spray foam urethane resins do not usually have any problem sticking to anything that is clean and dry.
It was sure stuck to the inside of those doors. It took forever to dig out enough foam, to be able to weld patches in the doors, without catching everything on fire.
The rot was always at the bottom of the doors. So, clearly the moisture was accumulating there. Though, I am not sure exactly how that worked.
The side, and rear doors, did not have any openings to allow moisture into them, like a front door does. Leaving only condensation as the source.
