This is what passes for "finished" on this repair at this point. I thought I had a couple of more in between shots, but none materialized.
I'm working my way through a series of rust repairs, and am in rocker panel hell right now, so, ground mostly smooth with a shot of epoxy primer suffices as finished until I come back around to fill and smooth out the visible spots. Lord only knows when "finished" will mean paint, reassembly and actual driving.
