If you have a NIB game, I would play a couple of games first to see that the machine works like it should. If you are happy that the game is ok, only after that I would put the protector in. Otherwise the manufacturer might claim that the faulty operation of the pinball machine is due to the end-user messing around and installing a PF protector.

Oh, and a definitive downside to me is the "sweaty look" that sometimes occurs under the protector. These are so-called Newton rings and I have yet to discover a proper way to get rid of them. I do not know if the occurring of Newton rings is only plaguing a single manufacturer of playfield protectors, or is this a more general phenomenon among manufacturers.

Anybody with a solution on how to get rid of Newton rings when installing the PF protector? I have a protector on my DI installed at factory without any Newton Rings -phenomenon and then there are two pins where I've myself installed the PF protectors and there is the Newton Ring -phenomenon very visible. I had cleaned both PF:s before with naphta, if I recall correctly.

Yes, on my pins it looks exactly like there are blobs of liquid under the PF protector. Somewhat annoying.

Hmm - I have wet spots on my Houdini and Alien. Both playfield protectors are from playfield-protectors.com. I have factory installed PF protector on DI without the wet spots - I have no clue of the manufacturer of the protector there.

I also think its the new thinner PF protectors that are plagued with the phenomenon.

Hopefully I may hijack this topic for a small question. I am using playfield protectors myself and I like them very much. The new thinner material that is used apparently is the culprit for the newton rings phenomenon, but I can live with it, even though I am not fond of it at all.

Here's my question: I have the following three games - is it worth to install a PF protector on them in your opinion?
(Looking for answers from people that use the PF-protectors)

GB Premium - has ca. 1000 games on it and has dimpling already
MMR - has ca. 400 games on it and some dimpling (not so much as on GB)
CC - is a restored one and has a very nice clearcoated playfield. There is a minimum of dipling, which is hardly noticeable.

I don't know. I somewhere read long time ago that the instruction was to get rid of the wax first with e.g. naphta and after that install the protector. Any experiences regarding this from other playfield protector users?

Hi! Do you wax the playfield protectors also, or just clean them? Thanks!

Anyone experienced this kind of Newton Rings -phenomenon, where the playfield with protector looks like its suffering from smallpox or something similar?
I got my game from a seller that claims to have installed the playfield protector before any games where played. To me the game looks like it suffers from dimpling and a playfield protector has just been installed on top of the dimples and that's why it now looks quite bad - like its having a smallpox...
I felt the playfield protector with hand and it seems flat to me, so I don't thing the blotches come from any possible irregularities on the protector. On the other hand, after the playfield protector is in place, there should not be any new dimpling after that on the playfield, right?

Any other explanation for this or do you agree that dimples are the reason for this phenomenon? Is there any way to get rid of the blotches?

Any help from you is much appreciated, thanks!

I wonder if it would help, if I put some microfiber cloth with naphtha to a long ruler and tried to wipe the playfield with it? Anyone tried this?

Playfield-protectors.com suggests blowing air under the protector to remove "wet spots" - has anyone tried this and what kind of experiences do you have?
