MG MGB and MGB GT Tech Talk
Has anyone used a metal adhesive, such as Lord Fusor, instead of welding, to repair/patch unibody structure or body panels? According to the manufacturer, these adhesive agents bond as well as welding, don't deform the panels and are impervious to corrosion.
Do a search on it. There's been quite a lot of discussion this. One was done within the last week or two, I think.
I have used it to hold a panel in place, and have then welded.
It OK , but call me old fashion..............but I would not fill happy
just using
the adhesive.

Quite a bit of discussion on this and other forums about adhesives. My take is that for them to be correctly utilized the structure must have been designed and engineered with these in mind. Panel overlaps and surfaces were engineered to be able to take enough adhesive coverage to acheive the desired strength. I'm not sure that this would apply to the MG which was engineered to be spot welded and panel overlaps engineered for that type of fastening. Until I hear from a qualified automotive structural engineer who had run the joint under simulated fatigue testing, I'll stick to welding just to be on the safe side.
Mark, i used 3m #8229 Bonding Adhesive for some repair panels, (not structural) and also a metal patch behind the door skin for the "COD". It did alI I expected. It does require a dedicated applicator gun, but a local Body Shop lent me one. A F/G rear bumper was also mounted with the #8229 since the brackets had to be attached to the F/G cover. It plainly states not for structural panels where welding is required. Apparently many body shops use it.
Saw them used on Myth Busters, they don't work...............
Used fusor for my floor pans on the 72.. 6 years and it's all good...

Same here. All good.

Epoxies work fine for UNSTRESSED panels (lower door skins, fender flairs...stuff like that). Use pop rivets to hold the repair in place while it cures. But you will have a VERY difficult time selling the car with this type of repair, even if it's done perfectly...and it would be unethical to not disclose this if you sell. I used epoxies in my younger days when I was smarter than everyone on the planet, with no ill effects over decades and tens-of-thousands of miles. But now that I'm much older and not as smart...I weld.
