I just brought in a Yamaha C3 (about 1973) for a new block and strings, etc. It had been restrung about 25 years ago (stringer evidently didn't realize that the bridge gauges were metric and strung everything one half size too big).
Anyway, whoever did it also sprayed the plate with "something" that was thick, not very durable, poor adhesion, now cracking and flaking. Looks pretty lousy.
Problem is, if I try to spray over this (which would now become the substrate), it is obviously going to do exactly what the substrate is now doing. Ain't going to work too well.
Any suggestions as to how I might get that off (back down to the original plate finish that actually doesn't look half bad, from what I can see) WITHOUT totally stripping the thing would be appreciated.
Is bead blasting an option? Never done it outside a cabinet.
I did not realize how weak this coating was when I estimated it.
