Just joined the club with a fairly rough Cyclone. 16-hours in the truck but well worth it I think!
From my reading it seems most Cyclones have mylar of some sort. Mine has small pieces in front of the slings and then the large piece over those. Leads me to believe that the large piece at the very least was not factory (and might come off without too much damage).
Based on these pics what do Cyclone owners recommend for removal... heat gun or cold air? I'm assuming most would remove it given the wavy areas in front of the flippers which I tried to show with some light shining on them.
