What’s some good adhesive for adhering metal to metal in auto body work? Obviously welding is ideal, but not too feasible in this application. Whatever is used needs to have some decent strength, it will be down in the rocker area on my rig, but behind my rocker protection. Rocker protection will actually bolt to whatever I stick on. I’ve seen a few options on Eastwood, but this is all new to me Any help is appreciated.

This is what the OEM's use to glue body parts together. Usually welded in addition, but they actually said for a while that you could JUST use the panel bond without welding. It does become brittle after it cures, so if you will be bashing against it (under armor) it may not hold up without welding also.

Awesome, sounds like the 3M Panel bond is the way to go. Here is what I am doing, I damaged the rocker on my JKU when the crappy rocker protection/slider bent in to the rocker in Moab. I’m installing real rocker protection and sliders now, but I can’t bolt the bottom row of bolts in on the rocker armor due to the damage. The damage isn’t the same front to rear, and it’s made worse because I already pulled and bent in order to get the middle row of bolts in. All I’m gonna do is “glue” a 1” piece of strap in in order to get a solid surface to bolt the armor too. Here you can see a decent idea of the gap at the front, it gets to be less as you move back on the rocker. Because of the compound angles, trying to pull it out is pretty difficult (already tried)

Panel Bond is nice

Evercoat #100815 Maxim works for me. It is a multi panel bond adhesive and can be used in a pinch with a standard caulking gun. I usually grab my high ratio caulking gun and go at it without issue. It is a 2 part and comes with 2 discharge nozzles to screw onto the tube. The clamp time is 4 hours and will cure in 24 hours. I used it in 38 degrees and that took about the same amount of time to cure.
 
LORD Drip Rail self leveling seam seal. It can also be welded afterwards




LORD panel fuser 108b. Also able to be spot welded even after its dried so you get the benefit of completely sealing off two panels.

 
I've been happy with 3M 08115 2-Part Panel Bonding Adhesive.
But as stated above, you need the correct gun to be able to squeeze both A and B parts simultaneously.
 
I hope I don't have an issue with embrittlement. Fiberglass bonded to metal seems solid. Rocker was caved in like op so I overlapped with aluminum and used toggle bolts (like drywall) to reach the deep spaces that couldn't be clamped. Beat to fit, fill w/ seam sealer, paint to match.

Some GM cars since the mid 2000s have had the roofs glued on. No metal to metal.
