It wasn't you Larry, it was Kabwe.

Oil canning? It refers to the old timer type oil can that had a spout, and you tipped it upside down, put the spout where you wanted the oil, then pushed on the bottom of it with a finger and it flexed a bit and pushed the oil out of the can. Oil canning on the sheet metal is when its easy to push, kinda flimsy.
As far as rust, on mine I was going to use a small hose and a solvent type gun and blow in some zero rust paint.
