I think a dry wipe pen might work, the ones used for writing on whiteboards and such.
I think i have one of them pens about somewhere so i'll try find it and give it a whirl on one of them bike Texas Hold'em Rules cards. I would have never thought they'd have a use
 
Edit: Nope they dont work
 they wipe off a bit but not fully.
