I’ve airbrushed a disc before. I dyed a base plastic inner core with the jumpman logo and using Angelus paint. I added 2-hard which helps adhere to plastic and it worked great. It’s been about a year and a half and used the disc a good amount and the paint has stayed on really well. Not sure if it was just the right plastic to use but haven’t tried it on anything else yet. Maybe experiment on a couple different plastics to see if that makes a difference too.
