Microsoft reminded me of "memories of this day" for a fix I did years ago.

 

There obviously was some sort of solvent (most likely nail polish remover, a kind of lacquer thinner, usually) on a dining chair.   The fix was just to apply some clear touch up lacquer, let if dry, probably with some help with a hair drier.  That just took a minute or two.  Do some light sanding.  Repeat until it's level and color returned.  Sometimes, you need to apply a final coat of lacquer over the whole thing to match the sheen.  Lacquer will dissolve layers below, essentially making one layer of finish, unlike other finishes like oil  and waterborne poly where the layers are always distinct.  They also  take much longer to dry, so a quick on-site fix is not possible.   In my 20 or so  years of furniture repair, I think I had 3 pieces that were not factory finished  with lacquer of some sort.

This, and burn-in repairs, were done 4 or 5 times a day many days.   Also in the portfolio was cleaning upholstery.   Less common, but always in the job list, fixing upholstery by sewing, fixing power and manual recliners, and what I called "structural repairs", stuff like broken or separated wood parts.  I also did a lot of strip and refinish and kitchen cabinet refreshes. Never a dull moment.

Great job on the chair. For me Lacquer was difficult before I discovered that a small bypass airbrush from Harbor works very well with lacquer. The key is to apply enough to wet the surface but not so much that it is oversaturated and runs. Yes I know that sounds impossible and it is a learned thing but it just takes practice.
