Good Thread!
I drill on the lathe, use a rat tail file to smooth the inside of the blank, paint 2 coats of Cremecoat (Michaels) on the blank, spray paint the outside tubes themselves with the same color, then use a similar color of testors to color my epoxy. I usually wait overnight for each step.

I do, however, like to use pink on pink blanks and likewise with green and purple. I have found that testors small spray cans match their colors for the small enamels.
I have gone to this method to eliminate "tracks". Does this sound like too much trouble? I never have issues anymore, but it seems like I am jumping through a lot of hoops.
