Any bending or misalignment of the bonded joint, and you will be back where you started, hence, the sam mac recommendation of welding.

Actually, the stick product they sell at gun shows and flea markets that can be applied with a torch (propane, mapp, etc,,,,) does a pretty good job,,,

This would be a better application than their demonstration of sealing a hole in a beer can.

How do you get a hole on a beer can, anyways!!??

I understand the strength in compression, or shear, that is why I put the 1/8" plate on (for the tension), to help with support. The back plate is mostly for support of the S/G back end. The way Q-Bond is applied wouldn't seal a hole in that beer can. You fill the crack with a powder, then drip on the super glue like adhesive. You get powder for plastic and a different powder for metal.
