I actually did both methods on playboy 35th. Playfield looked great after removal... but both methods are tricky, and i would recommend freeze over heat. too easy to screw things up and pull up the art work over inserts.
most likely you still will have to do touch ups though..

if you can get machine for 500 or less US dollars, then go for it.

Our playboy looked exactly the same. We did a successfull mylar removal with freeze spray.

I have a question, has anybody ever tried very low pressure compressed air? Say with a ball inflation needle into one of the bubbles and very slowly add pressure. seems like it might work. But i could be completely off my rocker.

Mine looked the same, I did it with heat.

IMHO the paint of these DE's is not to be compared to System 7/11's. Pretty robust. I clean mine off in about 2 hours total. ZERO paint/insert lift.

Sorry, I only have Pre pics. I traded the machine to PWA and did the removal in the backroom prior to Sarah taking possession.

With the Mylar off it was a NICE machine.

Well i lifted the mylar on my GL with heat, worked like a charm and like very, very minimal paint lift.

Nemas problemas, the right method changes for every person, my friend tried freeze spray on his Black Knight mylar removal, that method seemed pretty much shit since it flaked off alot of paint on the upper part for him, then he switched to heat and it just came off without further problems.

I loaned his heatgun and just caught a corner of the mylar with my thumbnail, then heated while slowly pulling until i felt resistance, then heated more, kept pulling, heating etc etc

Went flawless for me, just some parts of the black on the lower playfield that lost some chippings, easy to refill and cover.

Older System 6/7 machines,,,, gah,, last time I tried to use heat on a Firepower II, I almost made a whitewood. So much paint came off.

Most other machines heat is no problemo and a lot less glue to remove after.

On my bro's Time Warp (1979) the mylar just came off with heat, barely even any glue left either + it was easy to rub off with Lable-Off spray.
