I agree with viperrwk, I wouldn't do it! I used the freeze spray method on my Cyclone; the mylar came off with very minor paint loss. Would have been an easy fix and would have looked great. I used Goo Gone with a plastic razor blade to remove the adhesive. All was working fine then the paint started smearing as I wiped the residue from the playfield. I had to pick up another playfield.

Yes! This one is very touchy. I tried heat and freeze spray. The freeze spray method worked best. Cleaning the glue off can be difficult. Naptha worked best for this. Orange power was surprisingly to aggressive and removed ink.

If the mylar is still sticking good to the playfield. I'd suggest just buffing it out to a nice gloss and leaving it.

Novus 2 and a good carnauba wax, I like Mothers. I use a Wen 6" random orbital polisher.
