What is the best way to remove "blistered" Mylar?

[AndyB53]

What is the best way to remove blistered and broken mylar? I suspect careful use of a Heat Gun and patience on a stripped playfield is the answer.
Anyone with a better solution? (and dont say 80 grit sandpaper)

Hairdryer/heat gun followed up with the flour method for removing the glue is the best way I've found. I did this on a Fireball 2 and went nice and easy and it came up lovely. If it's on a diamond plate playfield then you an afford to be a bit more aggressive if needed There's some pics and info in my old Fireball 2 shop log thread:

Thank you! I wonder if WD40 will help soften the glue as I know it does not damage the paint/ artwork?

I'd steer clear of using WD40 on a playfield personally. Looking back at that thread I was using label remover along with the flour but these days I'd go with IPA instead

I wouldn’t a lot of clear coats and paint don’t like ipa. Stick goo gone and flour or ecostick adhesive cleaner

I've had good results using an air can (ie: freezing the glue) and removing, from a diamond plate playfield.

+1 for the Goo-gone + flour glue removal method.

+1 for the air can freeze spray method, I used that on my Fish Tales without damaging any inserts or paintwork.

This fella does a comparison between the heat gun / air can methods:

SPOILER ALERT air can wins

 

[ronsplooter]

The freeze method is good for diamond plate/cleared playfields and where the mylar is still in one piece or large sections. On older playfields I prefer the heat method as it's more controllable and I feel I'm less likely to take paint or inserts up If the mylar had broken up into loads of little bits then I'd go heat method as well, just a bit easier to manage IMHO.

I did the freeze spray on my BK2K which is supposed to be a nightmare - came up okay.
