I ave a green Cutter and love it, however, I’m having a hard time getting the paint to come off. I fight all the time on CNBC, as I’m working on Elite in combat. 50% deadly now, and my goodness it is taking a very long time!
It's just from time in supercruise. Point the ship in any direction (with enough fuel) & leave it going for a couple of hours if you want to wear the paint down. It'll cost you a fair bit to repair the hull integrity in a Cutter.
