If you use ETEX or another clearcoat that contains solvent, you can't use solvent based pens to sign or draw details on your bait - that includes Sharpies, etc. The easiest solution for me was to buy a fine poiint calligraphy pen (less than $5 at Michaels, etc) and use Createx black to sign the lure. A calligraphy pen is basically a plastic stick with an old style fountain pen nib attached to the end. This works out well because black is the last color I use for kill spots, etc on lures - so I just dip the pen in the airbrush cup and sign it. And black Createx flows through the pen tip better than any other color due to its small pigment particle size. It makes finer lines than any Sharpie. My signatures still look like crap but at least the lines are fine and never smeared
