Welcome to LTG, sorry your first post has to do with a problem.
Blue Book estimate for that guitar runs between $1350 to $1650. So on that basis, it seems that you might have overpaid. No one likes to be taken advantage of as it tends to color our outlook and enjoyment, at least initially, of what is a very nice guitar.
Other than the cosmetic finish issue, how do you like the guitar? I play an '80 F-412, and can't get over the sound...it's one of the nicest 12'vers I've owned. You mention that the guitar was NOS, New Old Stock, and would you be considered the first or original owner? If that's the case, your guitar would be covered under Guild's Lifetime Warranty...and the finish could be repaired under that warranty. Is the store an Authorized Guild Dealer?
It's obviously left a bad taste in your mouth. Good luck....
David
