If no one else comments i just wanted to say that i used a single epoxy paint with no primer.
it didn't work. I would suggest cleaning/ primer/paint
Someone will probably comment though.
Sorry I can't help
I painted mine with regular Rustoleum enamel (red and blue). You do need to clean wax off with a toothbrush and lacquer thinner. I did mine 8 years ago still looks great.
I have great luck with Testors model paint, you can find at any hobby store.. Get a small bottle of primer and red and blue flows nice with a small hobby paint brush works excellent should last forever.
