In the end I had to use a combination of Magic Erasers and Goo Gone. This worked, but it took some time.

Did that pull up any paint? I've got a Whirlwind with the same issue. Mylar came up great, left a (mostly) beautiful playfield. But it's sticky. Nothing else seemed to help get off the glue. I've been too afraid to use a magic eraser.

I've tried everything. Someone told me crisco and i'm desperate enough to try it. At this point, magic erasers sound a slight bit better than lard.

This glue is tough stuff. This is the third machine i've pulled mylar off and the only one with issues. I agree with system 11 glue being the worst.

There is a full youtube tutorial in 5 parts on playfield clearcoating. This is exactly what I did, but I used better personal safety equipment then that guy did!

I'll be looking that up! Thanks!
