Your fingers work mostly on the shafts first 10 inches from the tip so that is where you would most appreciate the glassy smooth finish you will see in a very short time! I would never do this to a cue that I were detailing. Appearance is really not the goal here. A silky smooth playing shaft is!
For appearance if you need help try lighter fluid. It will definately remove the blue from the shafts. The only drawback about using the lighter fluid is your shaft will need to be resealed after it is cleaned to properly protect the shaftwood .
