I did something similar to what you might want to do, I think, I had a sneaky pete that I bought for like $30 a while back and just as a little project for myself what I did was get some sand paper (rough and smooth grit) and sanded the clear coat off then I got some wood stain and applied it with a sponge brush and then I brushed on a new clear coat (polyurethane). If the cue cost some serious money then maybe you should let a cue maker repair it, but if not its a good way to kill some time. And after I finished the cue it actually looked better, I used a walnut stain and I think that gave the cue a more exotic and older look. So if the cue isn't worth much maybe you can go to a paint/hardware store and explain what you want to do and they could show you what you need.
