I've never had great success with mylar and novus - although will clean a pf very well.  I bought the TC kit mostly for diamond plate games which it does very well, however it works on mylar quite well too.  I spent about 25 min - about 5 passes in total and I think it came up well.  BUT it does make a huge mess - so ideal to remove the playfield out of game and all playfield parts too.

Which one's the before shot Marty??? Just joking, I've got the TC kit but haven't tried it yet. Have you heard of anyone using it on a non diamond coat PF?
