What finish? I’m using the standard Dunlop stuff at the moment which seems fine on everything. I used to use some stuff from Meguiars on my satin les Paul which always worked really nicely
Mix of finishes really, but a gloss acoustic, a flatter finish old Rickenbacker (lots of crazing and cellulose cracking) that's really 'sticky' to the touch. Not sure that can be transformed really, could probably be doing with a re-finish
