It's really an easy task.
Buy some 3M sandpapers.
West 207 epoxy for basecoat.
Dupont Chroma Clear is a good choice.A SATA gun , clean compressed air , high speed buffer and some compounds.
You'll be set.
Joey,
Given the recommendation of Chroma Clear, didn't you leave out 1) a Respirator, and 2) a Spray Booth with an outside exhaust? :smile:
On a more serious note, finishing is indeed one of, if not THE most difficult, of the MANY skills that go into building a cue.
Skinny, since you've got a SATA gun, I'm going to guess that you have some finishing or painting experience. It should be no surprise to you that you can't just spray some canned clear over the top of your already finished cue and get a guaranteed result. Some finishing compounds simply don't get along with others - no matter how long the base has dried/cured out. It may work out fine, but it may gum up and be a disaster.
But you've already received some great advice here, so pick what seems the best to you and go for it.
But, I agree with several others, you could be more humble/polite given that you're the one asking the questions.
My 2 cents,
Gary
