Made it to a milestone. Rust repair done
At least I think so. Finished up both spots behind the wheel wells on the bed. Other side had a surprise once I cut out the bad spot, so I had to cut even more so I could fix the area behind. I hadn't bought a patch panel for this side so I ended up welding the original metal back in with the smaller patch in it. I think both sides are now ready for a little filler. In fact, that's what is up next. Lots and lots of bodywork.
