Thnaks Nino & Marty for the advice. Looking at my playfield, the mylar seems to be targeted at specific areas ie. the open area portion of the playfield starting at th eshoot again insert all the way to the skull opening. There doesn't seem to be many things populated around these areas. So I'm thinking remove everything bar pop bumpers, canon and the skull. The mylar around the pop bumpers is still quite good. I wasn't even considering of removing the playfield as I'm not going to mylar or clear coat, just wax. T2 probably gets 100 games played per year.
What do you reckon, or is there more reasoning behind removing everything that I haven't considered?
