Quoted from f3honda4me:Wax the playfield regularly and change the balls regularly. You’ll never need the protector. People posting pics of abused destroyed play fields as if that’s something that will happen in a maintained HUO game are being intentionally misleading.
I have four HUO pins in my collection and three of them have playfield protectors on them. The gameplay has been dramatically improved on all of them (plus they look great too).
All of these HUO games have the original playfields except for one... the Rolling Stones. It has a fully assembled NOS Bally playfield that I removed from the original wooden Bally crate and installed in my pin. NOS but not without flaws in the insert heights and a few other minor cosmetic flaws. With the playfield protector installed (which took about 15 minutes to install) not only does it look better (almost like it is clear-coated) it also plays much better. Nice and smooth.
This is the best option for these type of machines with less than perfect (but still super-nice) OEM playfields.
I can always strip the playfield down and have it clear-coated. Nothing changes in that department. I can remove the protector in a matter of minutes and the game is exactly as it was when the protector was installed.
Don't knock these until you try one. You are only risking the cost of the protector but if you are like me with some ultra-nice original pins that you don't want to have the playfields clear-coated at this time, it's just the ticket.
