Post subject:  Gibson neck finish crack

Hello friends.
Help me please with advise. I have Gibson guitar with finish crack on the neck (I attached the photo). How can I locally refinish the neck to remove that crack?
Thanks!

That is a structural crack in the wood from what I can see in the pictures not just finish. Where on the neck is it cracked?

The crack is near the neck pocket (if I use correct terminology). Red line marks where the crack is.

I agree with Fred . I dont believe that is a finish crack . Looks like structural to me. If I were a guessing /betting man , I wud say its a stacked heel and its coming de-laminated at one of the stack joints . If im right that would require removing the Neck taking it apart at that joint and re-gluing the stacked heel and then re-setting the neck

Is it possible for example to remove the finishing just around the crack to see whether there is a structural crack too?

That Crack is way to uniform NOT to be a crack in the heel . Yes you could sand back the finish , but thats what your going to find. You might however pry it open slightly just enough to get a syringe of glue in there and clamp it . If you will check my thread here you will see I have one almost identical that I have just cleaned the pocket out on

Sorry, I didn't get where is your thread with similar problem? Can you please give a reference?

Been through this a bunch of times in the past... Wait until it really breaks, OK? Otherwise, all you are doing is setting up for a long period of touching up the lacquer finish. Sometimes this is all the worse it will ever get. Just be patient, and wait until service is actually needed. In the meantime, play the thing.

Now that I see the location of the crack, try pushing the neck forward and see how much movement is in the crack. If there is little or no movement I would carefully wick some thin CA into the crack which will help stabilize it and seal the finish.

This is exactly what I've said to my friend (this is his guitar). :)

Yes, I tried to push the crack and it is totally steady. Thank you for reminding about CA, used this trick but forgot about it...

I tried CA. After sending and polishing - the crack appears again as a tiny hair. Maybe the crack is too small for CA to hide it?

It's structural and should be repaired. The fix is to pry open and insert glue, HHG, Titebond original, and clamp.

The finish touch-up is where most of the time will be spent.....

Your not going to hide it . The only thing you need worry about is structural soundness . You want to hide it will require refinish of the entire neck .

I would not advise using CA glue at all.

1: It can damage lacquer and will not fix the problem with the finish.

2: Using it on this type of structural joint is risky as it will be prone to failure and will be more difficult to repair when it does.

An earlier poster was right. Wait until it's really broken-broken and is effecting the playability of the instrument. A more effective repair can be made at that time. Repairing the finish now will do nothing as it will just keep cracking.

Once the joint is properly repaired, the finish can be repaired by either drop-filling (with nitro), shooting a coat or two, and sanding/buffing; or, a neck refin - this should only be necessary if you want it to look as best as possible or if the joint is stable but didn't go back together clean enough for you.

Hope this helps.

Thank everyone for the help.
I decided to leave it as it is till the situation changes.
