Aye, body work is a long and boring process imho. Bang out dents, glass if need be, fill, sand, fill, sand, etc.
I have over 2 hours of just sanding for a 6x6 section I replaced using some metal patchwork for drywall (bondo sells same thing but 3x as $), bondo kitty hair and bondo filler. I wanted it to turn out good and it shows since it looks damn nice. Friend thought I paid to have it done.
Sean, its coming along great! I admire your work ethic and commitment to getting it as damn near perfect as possible.
