I know the feeling. I can do body work but hate it. Always looking for a way to avoid it. Best thing is to just get at it and get it done. The longer you leave it the harder it is to get back at it. The last time I had to take a break from the Dart was midway through the body work stage...all block sanding, which is my least favorite. Took me forever to get motivated enough to get back at it. Biggest thing that keeps me going now is finally seeing the color go on.
