I usually use House of Kolor high build poly with a gun, but since this bass is being built on the cheap this particular poly is Minwax spray can. I applied it like this: 4 coats 10 minutes apart, let cure, wet sand flat with 1000grit, 4 more coats 10 minutes apart , cure, wetsand 1000grit. Its currently at this stage, After it cures this time it will get 8 succesive coats (really wet ones;) ), cure, wetsand progressive to 1500 grit, buffed, polished, glaze, wax. The minwax takes a while to cure well enough to sand so that sucks, (House of Kolor is good to go in 24hrs) But on a positive note it seems to recoat good and "burn in" well. Ive done instruments with the minwax before and it seems to hold up nice, takes forever to fully harden though.
