The toughest part I had was welding the top near where the sill plate is. The rocker panel I used (Sherman) was not very good for figment at all, and some of the contours weren't right. That top curve where the gasket goes was not as abrupt, so trying to get the metal close enough together to weld is tough. Plus just about every corner in the front and back had been cut for better fitment against the "A" pillar and "B" pillar.

They also make a weld-through primer. I have never used it but I'm going to try it when I do mine..... Lots of info on the net about it.
