I looked at this post http://stunthanger.com/smf/index.php?topic=28836.0 and went looking for the pens that Crist posted.
I did not find them at Office Depot, but found this one at Hobby Lobby across the street.

I put two coats on a some scrap. I put a few lines down and tried to remove some. It came off easy with rubbing alcohol. I put another coat on top to see if the ink would run or wash out. The ink lines did look just as bad as when I put them on. I am no expert at doing ink lines.

This is only a test and thought I would share. Could this be an option?
