Due to some unforseen circumstances, My F Bass is now without paint. This is a player's bass and won't be let go. I need a strong, hard, clear finish over the Ceruse job I plan to do. Should I use wood hardener or a thinned epoxy/superglue as a sealer under the finish to help with inevitable future dings? will spar polyurethane be enough? I have plenty of time and can get professional results with my effort. I've tried two auto shops. NEVER again. They are used to painting large, FLAT surfaces, all due respect. I gigged the bass carefully and COULD hear the difference. It sounded BETTER with a finish on it!! More focus, more bite, more TONE!! HELP! Need a finish! Thanks TBers!
