Hello. I want to paint my fretboard like a rainbow, with different shades of color associating with different musical notes. I was wondering what you guys think is the best kind of paint to use.

It needs to be durable and not flake off, it is meant to stay on during performance. Its not a show piece.

Right now the only thing I can think of is somehow sealing the paint once its applied.

Lemme know if you have any first or second hand experience with this.
Any suggestions are welcome. I'm just considering my options right now.

I haven't tried that. If it's Maple, you'd probably need to strop the clearcoat, apply a thin coat of primer so that the acrylic colorcoat can adhere properly. For clear, I'd use Polycrylic, pretty tough.

Do a mock-up.

Good Luck!

Why can't you just mask the frets off?
You don't have to take the frets off, you can eighter mask 'em or polish the finish off afterwards.

I did it once and I just knocked the finish off the frets with a fret file the same way you would normally recrown frets

Flats might make it last longer, and are a fun experience in themselves
