I have a Takamine EG334RC that the finish has developed a white haze on about 60% of the guitar (see pics). To my knowledge, the guitar has not been wet, but it's not impossible. I have read a lot online and tried most of the solutions mentioned with no luck. I have tried jet spray (lacqer reflower) to release any possible moisture and have even lightly sanded a small area to see if the haze would diminish. None of it helped. Do any of you have any thoughts?
The guitar is a Takamine G Series so it isn't the best guitar on the market. However, it was my 1st guitar so I'd like to fix it and keep it.

Looks like blushing to me. Where, generally speaking.... are you located and what's the humidity like? Has the guitar been anywhere else lately, basements, other climates, etc?

I am in GA, so the humidity is rather high here in the south. It was stored in a location that was not climate controlled.

If you can lay your hands on some, Roland (the keyboard folks) make a guitar polish that will take that off in a jiffy! Frankly, it's the best guitar polish I've used in 40 years.

I'm afraid the bad news is that the finish is not repairable. As far as I know there are no solvents that will soften and amalgamate the finish the way one might when working with lacquer. It looks as though the finish might have partially delaminated. In any case, stripping completely and refinishing brings the cost of repair vastly beyond the resultant cash value of the instrument so I find myself with no pleasant alternative to offer

WOW! seen some bad things happen to factory finishes but this one is a top 5!

Looks like a severe delamination...the whole clear coat is separating. Polyester like this finish does not absorb moisture after curing, it is physically impossible as the completely closed. That is also why it is hard to strip.

This most likely had it's genesis at time of manufacture. Either improper prep between seal/fill/clear or the sealer dried out before the top coat. Either way iot will not get any better and will likely continue to slowly degrade. There is no known way to repair except to strip and refinish which would cost more than the instrument is worthg....

Thank you all for the replies. I think I will just leave it alone and let it be. It's still playable, which I never do because I have other guitars I like much better. Just thought I'd tap into you all's knowledge on it.
