On the top side of my Mira, right around where the arm reaches around to strum, I have noticed that the finish has started to crack and chip away. I wasn't bothered with this immediately until over time I noticed that the finish holes have gotten bigger.
Also on the back of the guitar there seems to be a bubble in the finish and several dents. The overall finish seems to be very soft.

How can I stop the finish from further eroding and/or fix the finish to bring it back to new?
