I recently posted asking opinions on whether or not I should attempt to remove some badly applied mylar from my Old Chicago. The playfield is planking pretty bad and the consensus was that I should NOT remove the mylar because of the high potential for paint damage. Since I'm going for a preservation and not a full restore I completely agree with this. One of the members on that thread mentioned a playfield protector as an option. I've been looking into the playfield protectors and they do make one for Old Chicago. Does anyone here have experience with protectors? I have a few questions about them that I can't seem to find answers to as they pertain to EM machines specifically.
-Will the protector lay down correctly on top of the mylar that's on there? Particularly around the edges and the parts where the mylar is sort of stacked?
-Keeping in mind that the playfield is planking a decent amount, will the protector affect it negatively at all?
-Also, am I correct in thinking that the protector has no kind of adhesive on it at all? If so, what exactly holds it down? Is it like a window cling sort of thing? Or does the weight of the material combined with playfield pieces hold it in place?
-If I do put a protector on, should I wax the playfield first?
