So I finally built up the courage to pull the mylar on my TFTC. There was already a bit near the outlane where it had raised up a bit so I thought it would be easy to spray under there and use that as my starting point. When I gave the mylar a little tug, a tiny piece of the edge just broke off. I grabbed another piece and again it just cracked off as though the mylar was really brittle. Now there were no raised bits left in that area, so I moved to another edge and started to pick at it with my fingernail. The mylar just started flaking off again! All the pics I've seen, people just seem to be able to get it off in one piece. What am I doing wrong? It's going to take weeks to chip it off bit by bit!
