Here are some wheels I painted in 2008?
The wheels were sandblasted, and sprayed with PPG 1790/1791. Then DPLF/ DP402, then Dupont Centari/793S.
I did not use the Featherfill.
Each time I did a painting step, I would paint the backside first. and then the front side. That way the over spray ends in on the back side of the wheels.
I laid the wheels flat on a masked off board, on three broken pieces of a paint stir stick, to minimise contact spots.
