With the mixed reviews I'm wondering if there was something else going on with this original posted protector like a bad batch of plastic. I've had one on for half a year, played hundreds of games on it and still looks as good as new and wayyyyy better looking and faster than without it. From germany too (0.02" PET-G) I think the same as original post. I lightly waxed it once when new and never needed to since. I still haven't seen a "wet spot" except for the 1 time I had cleaned a small spot on the topside with windex and a tiny bit got underneath (my fault and all I had to do was raise the playfield slightly and it evaporated away in 12 seconds). I'm wondering if humidity control might be necessary to reduce what others are seeing? I've got a dehumidifier set to 55% which might be helping here. Are these wet spots actually wet or is it an optical illusion? Or maybe people are talking about a variety of protectors like thin mylar vs PET-G vs other kinds and we're all having different experiences as a result... Put a new ball in with the new protector of course!
