How'd you remove the mylar? I bought a 1977 Cleopatra playfield to tested a few methods. Freeze no good at all, but shellite and the a sunny day seemed to do the trick. I had a bit of paint loss in the beginning, but found that it was more due impatience. Lost little dots of paint in areas again from going too fast. Is that what you found or is it more a matter of luck of the draw?
The playfield still looks awesome and much better than before. The residue if its glue, you try to brush shellite like mad in areas to test if it comes up 
good luck with the project 
hi mate i tried shellite and heat on my last pinny (1980 torch) and it worked pritty good but on this i tried to use white spirit. but found i was losing little dots no matter how fast or slow i removed it so i tried with heat from a hair drier and it started removing much easyer. but still lost bits of paint. i think most of them little dots u lose are just luck. cant stop that. but i found that the white spirit removed the mylar but left nearly all the glue on the play field. but when i used shellite and metho on my torch with heat most of the glue stayed on the mylar. it could be because they used different glues on the mylar im not shore but there was a hell of a lot of rubbing and scrubbing to remove the glue from the time warp.
i lost the most paint removing the sticky plastic rings from the pop bumpers. wish i new i would of left the ones that were not so bad.
