I'm replacing a quarter panel on my '85 FJ60. I'm pretty new to this kind of work and I was wondering if there's a trick to separating the body panels after the spot welds have been drilled out. Some of the sections come apart easily and others are a royal PITA. I tried cutting beyond the spot weld but still have the same result...seems like there's something else holding it in place. I thought about using a heat gun but didn't want to warp the steel, and wasn't sure if that was the best method. Any help or advice would be greatly appreciated, thanks in advance.
