Twenty coats!
I've done sparkles on a surfboard with one coat! Sanded and polished it the next day. You guys are all nuts!
Why don't you coat the sparkles with a layer of resin??
This guitar has a polyester resin finish...
Tape the edge:
Pour over the resin and spread it out with a brush:
Alls you gotta do is paint on (with a brush) a very thin layer of resin, sprinkle the sparkles, wait an hour for it to cure (not dry - you can control the time) and then pour on a 1/16th inch thick layer, then spread it out.
Most resins are thixotropic, which means if you push them hard when they are liquid they act like water, but when you leave them alone, they act like cold honey. It's this thixotropic thang that lets you do a very thick layer with gravity making it lay completely flat.
Sand it the next day!
I'm gonna have to do a bloody sparklecaster now!!
