so i read on reranch that metallics are a little tricky.

they said you cant sand or really do any thing to a raw metallic finish.

ok so heres my situation: im going to do a two color polka dot finish on my guitar, i plan on having metallic purple polka dots.

so im gong to paint the whole body metallic purple first, then im going to mask off circles, on reranch they recommend that you clear coat metallics, soo should i put a few (4ish) coats of clear coat on before i mask (i was planning on doing this any ways), and how long should i let it cure before i start masking?

I've never worked with metallic paint, but What you said sounds right. Prolly do about 5 clears, though. You can work with the clear coat after a few (like, 2 at the most) days, but be careful, as you can still smear the lacquer or leave dents in it if you set it down on something. Just treat it like hard paint and leave it hanging up as you work on it. Just be careful is all I can say... Lacquer takes a month or 3 to fully harden.
