wow, you got me! i'd contact folks who repair instruments for a living. there's a group of folks in hawaii who custom make strings, i bet they'd know how to repair a finish. i bet the veneer is ULTRA thin.
I remember when you first recommended that channel to me. I've been binge watching him. Great stuff.Dave,
If you want to learn about repairs to wood finishes and patching veneer, I suggest you go to the web site: thomasjohnsonrestoration.com, or his Youtube channel that can be found by searching for Thomas Johnson.
He details his repair work on antiques, with many veneer repairs. Great site and YT channel.
