Hi everyone. Thanks adding me. My daughter and I are building a double neck guitar ( probably a bit ambitious to start with !! ). We sanded the necks and body through to 800 grit. We undercoated with auto body primer and lightly sanded. We sprayed with a red metallic auto spray ( same brand as the primer) and left the paint to harden. We then gave the neck and body ( of the guitar ) multiple clear coats of auto spray ( again, same brand) and left them to cure for a week. We sanded the necks with 1200 then 2000 wet and dry ( with water ) , cut and polished and then wax and polished. They came up great. When we tried the same process on the body, we found bubbling around the holes for the dials and screws etc. . I have sanded the clear coat off the body and will repeat the painting and clear coat process. Is there a way to stop the bubbling happening again ? Thanks. Sorry the post is quite wordy
