Back to patching I cleaned all the blasting grit out of the cracks and crevices... then I cleaned out the car.
I've seen a lot of complaints about how hard it is to get blasting media out of the chassis, but honestly, it wasn't that hard. It did take a few hours. Before blasting, I taped off all of the holes and stuffed plastic bags to minimize what got inside boxed cavities. After blasting, I spent about 3 hours using a combination of the shop vac and compressed air cranked up on full to suck and blow the media out all the holes. When I was done, I couldn't hear anymore grit rattling around when I rotated the car, nor did more than a half teaspoon fall out. I'll go through it again before painting, but it seems pretty clean.
Yesterday I started on patches for all the nice surprises revealed after blasting. First up was that left fender that was hiding under Bondo.

To add insult, the side wart was stuck on with sheet metal screws instead of the proper clips. The plan was simple, straighten the panel, weld up the slide hammer holes, then patch the rusted metal around the wart. Spent almost a full day with shrinking disc and hammers and dollies to get the panel straight and smooth. Welding the holes went well until I worked toward the front and everything started blowing out just waving the welder nozzle toward it. Closer inspection showed dumbasses at the body shop had hogged down the steel to about the thickness of aluminum foil in spots. Time for plan B:

I measured the piece I cut out and the thinnest spots were down to 27 gauge!!!
Here it is ready for welding.

I thought about cutting another patch but fueled by stubbornness, I was able to use a copper spoon to bridge the patch to good solid steel. After grinding, I sprayed a guide coat and block sanded with 80 grit. After just an hour of hammer and dolly, I had the panel looking pretty decent. It will take a few more hours with shrinking disc and hammers, but I think this is only going to need a very thin coat of filler to mainly fill the shrink around the welds. After the hard fight, I'm ecstatic how it is turning out. And look, no wart hole.

Click to view attachment Click to view attachment One last thing. With all the grinding still ahead of me to get this thing ready to paint, I decided to splurge and bought two boxes of
3M Cubitron II Roloc grinding discs. On box each of 36 grit and 80 grit. For some reason, you have to swear you are a professional when you buy these.
I love these discs! The discs last about 4X longer than the 3M green discs I've been buying and the edges don't wear out. Definitely the biggest bang for the buck I've found.
