I’m currently working on a couple of builds (with thread and pics forthcoming, IF I can ever get them done). Simple basic black paint scheme (sans benefit of pearls) on both, with a gloss poly clear coat. No fuss, no muss, sanitized, biodegradable, and dandruff free. Base coats go on fine (typically 4-6 coats), clear goes on (6-8 coats), and then sadness ensues. I get good adhesion between coats, but when I get to the sanding phase, I’m plagued by sandthroughs and witness lines, and it doesn’t seem to matter what I try. Rattle can spray on poly, wipe on poly, wet sand, dry sand, start at 220 grit, start at 400... makes no difference. Last one looked like a survey map of Appalachia. Today makes the fourth time I’ve sanded back and started over (at least I’m getting really good at laying on a base coat!). “Frustrated” doesn’t even begin to cover it. I’m even mulling the idea of using System Three Mirror Coat as a top coat (already have it on hand to use on one of the fretboards). I have officially reached the stop-me-before-I-kill-again state. Any help would be so appreciated.
