Hey guys. I'm not sure that this is the right forum for this but here goes. I've got a semi-hollowbody Spector (Spectorcore) bass en-route. It's mostly black with the exception of inside the f-hole, which appears natural in the pics from the auction. I've seen them blacked out on other colors of the Spectorcore. This is completely aesthetic but it occurred to me before that I have no idea how to actually do this properly! Any suggestions would be very much appreciated.
