I didn't have much time to work on the R5 body panels, but I did have a little prep time.
First, I dug up the seven skin scraps that get painted red, and I roughed them up with 220 grit sand paper, in preparation for priming. I also removed about 4+ years of oxidation.
I then cleaned up the dust with paper towels soaked in acetone, because for some reason I think that helps. Nice and shiny!
Up next: Primer, followed by painting.
