Quoted from Manic:
Even my WMS games NIB did not have the halfmoon mylars preinstalled by the slings. They were simply in the goodie bag so an op could put them on if they like. For home use they are completely unneeded and frankly look bad...especially when the edges start getting a little wax or dust on them and then they really show.
I haven't seen a privately owned machine with those PF mylars in over 25 years... from any company... why not simply include them in the bag and not stick them down?
Otherwise the first thing people will have to do is to heat or freeze them off... or simply peel them off and who wants to risk doing that on a newly cured PF?
Well that's one mans opinion anyways.
I like the idea. I would use a playfield protector if it'll be available or use nothing and have the option to put mylar on the playfield
