Varnish is certainly a traditional finish for a DB, but if the OP is going to use varnish then he needs to use a good violin spirit varnish and not marine or spar varnish. He's not going to be playing basketball on it or storing it in the marina.![]()
If this is a junk bass for outdoor use then I think it's ridiculous to think about nitro or spirit varnish. I think they'd be abou the last things an experienced wood finisher would use in this situation. I agree with Arnold absolutely: spar varnish all the way. Don't get thrown by the marine nomenclature here: spar varnish is just an ordinary oil varnish except the resins are more flexible (to accomodate movement) and it's got some UV protection in it (to deal with the being outside aspect.) It's simple to use, easy to obtain, and it will do the job admirably.
