Yet more paining today.
The skin panels probably could have remained as-is, but I figured one more coat of paint couldn't hurt.
I was able to paint the outer layer of the back door today as well.
The skin panels should be done with painting at this point, although I thought that was the case earlier. I'm sure I'll do a few more coats on the back door panel. And I still need to paint the main body of outer layer of the skins, of course.
