I primed and painted a bunch of stuff, including the window frames and bottom doors, as well as rear window plexiglas mounting strips. That doesn't seem like it should take very long, but with 30 minutes induction on each pot of paint and 5 hours till you can flip the parts and paint the other side, it takes quite a while to prime and then epoxy coat all these parts. Plus, it's a little challenging to keep temperatures about 70 degrees when the ambient temp is about 40 degrees in a farm shed. I also trimmed all the front and rear plexiglas to fit and started assembling the doors, but only got the pilot's bottom door completely done.
