RE: Props and paint jobs
I would get the length of area correct, and use masking tape to mask off the area. Spray will tough in such a small area, I use a brush. for the white, I just dip it in a can of Rustoleum. I haven't had any balance issues, but they should be easy enough to correct with just a dab of paint added to the light side to balance it if needed. I fly off grass, so I have to repaint about monthly.
