See your handout: sharpies are unacceptable—they'll turn purple and are not opaque—yet they are labeled "permanent," thus I warn you of any pen that only says it's permanent with no mention of india ink.
If you have some sort of pen you aren't certain about I suggest before you do your final do a small test area on some scrap board. Let it dry for a while and see how it turns out.
Note: use the type links on the right to view more type that may not be in your book. Adobe has the most.
Don't spray crystal clear inside!
