Hey Humpalot!,
Its always a thought and a wish re CC a playfield. I don't have anyone to do it for me. Would be nice..
When I mylared the T2, I cut around all plastic posts and metal posts. Anything that was bolted down, coming into contact with the ball was done.
The other option is to repair around the pop-bumpers and only put down mylar rings around these. It will be a tough job to mylar whole PF with the amount of large areas missing. I would have to leave the window in.
I'm not 100% happy with the way the pf is polishing up at the moment. The novus is OK but still a little dull and dry (no wax as yet.)
I've lent my treasure-cove kit out but should be back soon. I will do a test spot and see how it comes up.
