+1 on that,
BUT how on earth do you precisely measure what type of finish will give you BETTER tone? don't tell me the 'luthier' or whoever does it will have a proper machine with bla bla bla to give 'proper range' for the french polish or whatever coating you will have on your guitar.
In any case, it's all a matter of trust. Like from what I gather from what the threadstarter has posted so far, he's happy enough that the shop has done his best, and for all the mistakes that they have done, they do have done the proper thing by consulting him and explaining to him what happened.
Do you think that the luthier's finish and the furniture repairman's finish will make the TONE sound better or worse for the guy? I have no idea.
and last but not least, i think somebody here mentioned before, as part of the rules and regulations, that if you have a personal issue, settle it through the PM instead? or did i see wrongly?
anyway, french polish or oiled finish, or just simple polyurithane finish...it's really up to his budget and yeah...i'm no luthier or qualified repairman/finisher...so take my words with a pinch of salt please.
I'll just want to wait and see what happens to the threadstarter's poor guitar. will the french polish work? i've got NO idea. haha...and how much for the french polish? i've got NO idea...so...yeah... all the best to you threadstarter.
