I don't use a towel, I use a paper towel. If you meant a regular towel it will leave lint. First let me say I have not ever done a decal. With any CA finish, I apply with the lathe on. Otherwise it will puddle and drip off of the bottom (also cover your lathe with a rag/towel below the blank). Slow speed, apply at the bottom edge of the blank and go back and forth across. Mack does a lot of CA finishes, if he doesn't respond, pm and ask him direct, you won't go wrong with his information. Look forward to seeing the blank completed.
God and family, the rest is icing on the cake.
I'm so far behind, I think I'm in first place.
