You'll need primer before you even apply paint, plus clear coat to stop it from chipping. If you can get plastidip cheaper than all three of those, do that.
I'm having some issues with my repainted Namco Arcade Stick, in fact it begins to melt during long game sessions, because of my hands warmth. Does Plastidip could solve this problem? Have you got any other solutions?
I'm honestly not sure whether that'll help in your situation. I've never heard of that, is it the paint melting or the plastic melting?
It's the paint, the plastic is fine
