French polish repair

Post by Renee Labordus » Thu Jul 31, 2014 7:47 pm

I have an older (well 2008) classical with a spruce French polished top.
It has nail marks and string dings which I want to repair.
I am thinking filling with zpoxy to get things started.

Any thoughts, alternatives, or recommendations?

Pictures?

For sure "not" Zpoxy

Are you going to strip off the finish?

Did not intended to strip entirely.
I thought I could just fill the nail marks, sand smooth, and FP locally.

Here is a pic of a previously repaired crack. The repair looks terrible, but the sound has not been adversely affected.
The nail marks are not very apparent on the pic. When I first got the guitar (used and sight unseen) I didn't like it.
But over time as I started to play it more and more, it has become one of my favorites.

Don't mind spending a few bucks having it refinished (only the top).

Here's the deal as I see it -- if those scratches are in the "wood" not just the finish layer trying to fill and apply more shellac will just make a mess and it will look really bad. Especially if there is dirt and grime in the scratches and dents. If it were mine and I wanted it pristine I would sand off the finish, remove all the scratches, dirt and grime, "steam out the dents" and prep the surface as new work. Then apply French Polish --- and a clear pick guard!

The truth is "finish coating never hides surface defects" especially fillers, and wood scratches -- and the higher the gloss the more amplification of the flaws. $.02

The scratches are in the wood without a doubt, so I am going to heed your recommendation.
I am not familiar with the terms "steam out the dents" however. How is that done please.

If I haven't thank you yet for all your help. THANK YOU.
