Primer is down. I use Auto-Air 4001 white sealer for the base. I use their dark sealer a lot as well, and will use that as a base for the silver areas.
Just for the record, white acrylic paint is the absolute worst for clogging a gun, so I highly recommend straining it, and apply with a heavier gun like pictured. This one has a 1.4mm needle, so it flows pretty well. I spray the white at about 40psi.
I am going to try a different brand for the colours this time. The Mission Models RC line has some nice colours and I've wanted to try them for a little bit. The shop I work for started carrying them a while ago, so I figured I'd give them a shot on something not too fiddly to see how they cover, etc. I'm waiting on a restock of the Auto-Air line at work.
The nose cone is going to get Tamiya primer, as the acrylics don't stick great to the plastic.
