I’ve got an acrylic/plastic panel that is going to be used on an arcade cabinet I’ve built. The edges need to be sprayed black to cover everything except the screen. I’ve tried once before, but the first coat left pinholes. After it dried, I tried to touch those spots up, but the original paint began to crackle.
I’m using spraypaint for plastic, but I can’t figure out why it would do what it did.
