Thanks Gavin, i'll have to remember that one if i end up doing any kind of CCing in the future. Come to think of it, in the past i DID manage to spray acrylic CC over permanent marker ink without problems a few times, and im pretty sure id used Artline brand markers. i can remember one instance where the inks bled, when i did my home made Vortex PF, that i had to fix.
