Gents/Ladies, I am shortly on my MPCA, and would appreciate any pointers (serious thoughts appreciated but willing to guffaw at witty but irrelevant comments) on the classroom stuff. Also any tips on getting rid of permanent marker from my nyrex? I used nail polish removing pads on my old nyrex but it didn't agree with it (works fine on fablon!)I know about lynx deodorant being effective, just wondered if there is anything else suitable. I used chinagraph pens a few years back, but again that was on fablon, is it recommended on nyrex? Don't want to find out after my 1st set of orders that they've smudged/can't get rid of the damn things. Not quite a nig, but 10 years in the cav has put me at a slight disadvantage on this course judging by the course content.
