I'm fixing up a cheap machine for my game room and the playfield posts are super yellowed. They look gross. Looking up the 1970's posts I feel like I'd spend more than the machine is worth in posts. I'm not planning on selling but still don't want to spend too much. I had an idea.... Novus 3,21. Then, airbrush white. Seal it with a clear coat enamel. I tested it on a hidable post. Thoughts, feeling, name calling?
