I need to mark a bolt plate for ONE guitar, so don't want to order Cermark, or Enduramark, but likely will if this doesn't wok out. I have sprinkled black powdercoat on steel just for line marking and it worked nice, and just thought that if I mix some liquid in the black powder, I might be able to spray a consistant thickness and get better results, but not sure what liquid. Thinking just lacquer thinner with a little urethane or even epoxy.

Or am I wasting everyones time - just order marking stuff. Will try it and let you know though.
