60's Martin O - fix it or not

Just got a 1960's Martin style O and boy does it sound nice. It's in great shape but has some finish cracks. They are on the back ,about an inch and a half long. There are about 10 finish cracks about 1/8 inch apart. It looks to me like maybe it was dropped and hit on the corner of the lower side of the bottom. They are only in the finish. I'm wondering if I should get a small brush and coat them with acetone, then finsh with lacquer. I'm afraid that the cracks being so close they will eventually pop the finish off. What should I do ? Should I just leave them alone? I just dont want it to get worse . Thanks .

Nothing wrong with an old instument looking like an old instrument.......................................

As long as there's no structural issues I wouldn't worry.
