Hey guys I had a quick question. Ive recently learned some new routines using gaffed cards. In one routine the spec. has to sign the card, and in the other I have to draw a window on the gaffed card. I was just wondering if anyone uses or knows of any erasable sharpie or marker so I don't have ruin a gaffed card everytime? I searched around on the Café and couldn't find anything. Any help or tips would be awesome. Thanks in advanced.

Use IPA (isopropanol) to remove most markers, It can be found in most electronic suppliers for cleaning, you can also get presatrutated wipes. (this is the stuff used to clean the heads on tape cassettes and video.

You can also use dilute acetone but I only reccomend this if you are experienced with the hazards involved.

Faber-Castell make a pen- Multimark 1525, it is permanent but with an eraser on the end.
