Prep fuselage bottom for primer. Sand, vacuum, wash, dry, rinse, dry, PrepAll, and tack the belly. This took about 2 1/2 hours. Shooting the two coats of primer took about 20 minutes. I still have a little orange peel in the primer, but nothing like before. This should easily sand out. Perhaps because the high fill primer is thick, this is normal. I'll let it cure overnight and sand tomorow.
