Quoted from pinmister:
I am not a fan of playfield covers. In my opinion they are way overkill and a waste. The only way I would consider installing one is if I was an operator about to place a machine in a very high trafficked area. If it is for the home-you would need 10,000+ plays for it to show a value. Most homeowners put maybe a couple hundred games a year on and eventually sell or trade down the line. Sorry for my rant but I think the overlays are overkill for HUO and are meant for heavy usage on location. Skip the overlay and just wax and put some mylar down for potential wear spots(rant over).
Well.. I have a dusty basement and I think they look pretty classy. Probably overkill to keep the glass clean but it's my first NIB and I want to take care of it.
