OK, I'm really deviating from this Propane Project, but I need time to think this tank thing out, and I look at all this Body Work, and I guess I just can't resist. Here the problem is as always, try to straighten a dent with Bondo near by and the Bondo cracks.

So the Bondo has got to go. I prefer the torch over a grinder, just seems to be a little more thorough, with a little less work, and way less dust.

As you can see it peals away easily. It does smell a bit, and that is probably not good, but neither is the dust, and you do have to watch so you don't catch something on fire, or get the metal too hot and warp it.
