Yes you can, but it really depends on what you know, and what tools you have.
You should be able to find "Lacquer Sanding Sealer" at the local Home Depot or equivalent. If you can spin the cue shaft to apply it, it's much easier. If not, just rub it in being careful to keep it from building up more in some spots than others. You'll want to apply several coats to get it built up, and you'll also want to make sure you have all the wax and other junk off before you apply.
Once you have a decent coat on, you'll need to smooth it out with some sand paper or a scotch brite pad. I would use 600 grit or so, but you don't want to sand through it. The goal is to get it flat. Then 800, and then maybe even 1200 or 1500.
You can go with a wax after that if it feels better to you. Not too much though.
To clean it, just wipe it down after you play. I use a damp paper towel followed by a dry one. You will be amazed at what the damp towel will remove.
Try that and see how it works.
