Pinhole Remedy After Welding Sheetmetal Patches?

Not correct. Oem's for the most part use weld/bonding techniques where the adhesives are spot welded through the on steel and bonding and rivets or welding on aluminum. It impossible to duplicate in the aftermarket without some high end welding equipment such as a Pro-Spot machine. The adhesives used at the oem level are a long way from 3M panel bond and the like. There is not an oem out there that condones gluing there cars together as a repair procedure. Gluing a car together will get someone killed if it gets hit again.

That's not true at all, who do you think makes the adhesive that OEM's use?? Answer, 3M, Lord Fusor, etc... The spot welds are just there to keep the parts from sliding around while the panel bond cures. You can cream an entire quarter skin on and rosette weld it where it needs to be with a cheap MIG. ASE procedures, as well as manufacturer recommendations for collision repair, call for structural panels to be adhered all the freakin time. Even aluminum ****. You're talking out your backside here.
