don't get me wrong, I get the volcanoes too but on most repairs of that era I see no clear direction as to where to put the holes. They're usually all in a straight line, as if the guy said, "this is the lowest spot I'm pulling here!", and because they didn't put the holes where they needed to be to roll it out, or perhaps didn't hammer down highs while yanking they create huge volcanoes. Seeing this is just a head ache to fix. I'm sure I wouldn't have done any different...I probably would have mudded over them to top it off.
Thought it was worth mentioning because the severity of that could be a determining factor on whether or not to skin. I did my mustang and it had holes all accross the door and as I was half done I wanted to just toss it but also didn't want to throw away all that work. I got to keep my original sheet metal allright...some odd hours later.
