I got some more of the welding done at the Votech class last week. I finished up the bodywork on the passenger side trunk drop off and the large rust hole in the outer wheel tub. Luckily the rocker panel rail end was fine. As I mentioned before, anywhere that there was a large concentration of body seam sealer/caulking is where the rust occurred. Once that stuff gets old, it acts just like a sponge and holds the water next to the metal until the metal rusts away.
Here's the finished trunk drop off on the pass side:
And here is the before shot of the rust hole in the front of the passenger side wheel well:
And after I surgically removed the rusty portions and welded in a section of the reproduction outer wheel tub, and finished the body work, seam sealer, and partially undercoated it:
And for comparison's sake, here is the wheel well from Gramma's 75 Firebird in all its sloppily applied seam sealer glory:
