Quoted from glpinball:
Hi all, I picked up a TAF a couple weeks ago and I have a question regarding the playfield protector. I ordered one and it came in but as I was examining the playfield I noticed some transparent material (Mylar?) on the playfield in a couple wear spots. Is this an add on to the original, will putting a playfield protector on over this be ok? I am including a couple pictures to show what I mean. It's fairly subtle/low profile so maybe it would be ok but I have never put on a protector before so I just don't know. Thoughts?

Quoted from pinballinreno:
If you are installing a full playfield Makrolon protector you can remove all of the Mylar.
I would just freeze spray the mylar off and clean up the glue residue with rapid-tac adhesive remover.
Wipe down with naptha and apply a coat of wax.
This would be sufficient to protect the playfield from the protector itself.
Yep just like pinballreno said.
Here's a simple video showing the freeze spray method of removing mylar:
Tho you have to be a bit careful which adhesive remover you use (apparently some can remove the coating or paint from the playfield). Personally, I use the flour-and-naphtha method (rub a light dusting of flour over the remaining adhesive, put on some naphtha (IPA apparently also works but I have and use naphtha), and rub. Basically like this video here
