Has anyone had any good or bad experiences using Fusor Metal Adhesives? I'm considering using it to bond my outer longs on and the long clamshells on. Then using structural rivets to prevent the unzippering effect of the bonded surfaces.

Pros I've read
1. Metal adhesives shear strength is greater than spot welds or the sheet metal being bonded.
2. Provides corrossion protection on surfaces being bonded (bonded surface)
3. No warping of metals, unlike welding.

Cons I've read
1. Bonded surfaces can unzip, which is why a spot weld or rivets ar needed along bonded seam.
2. Don't let it get into areas that you don't want bonded or filled.

Any thoughts are appreciated.

As ever, a glue joint is no better than the surface it attaches to.

Rusty metal? Yer gluing to expanding rust cells that never sleep.. Rust comprises ELECTRO-chemical cells. Rememember, there's a battery in yer car and it conducts through the body.....

Rub yer finger along the glue joint area before gluing? Yer gonna be sticking the adhesive to the oil film from yer finger.....

Did you notice that none of the repairs listed on that site are structural?
Yes, there's a bumper but it doesn't absorb stresses, impacts, and flexes from normal driving like the rockers. With todays plastic bumper/metal underbumper designs, the metal only has to be loaded once- during a crash. Then it's trashed.....

The rivets are really to minimize glue thickness. Too thick, the shear performance is lousy. Thin is best for shear so the rivets are used to pull the surfaces together. Depending on the pattern and rivet design (solid or hollow core), they can also help transmit loads.

Any idea how much pressure a rust cell can exert as it bubbles up? It's enormous and can exceed the glue holding properties. In that case the rivets can help unzipping.

That being said, it's one case to glue together new clean metal and an altogether different case to glue together old rusty metal. Honestly, have you ever coated a rusty panel with paint, glue or whatever and stopped rust dead in it's tracks???
