Quoted from chucksmith:
Yes, I've wondered this too. A better way to ask this question is...
Is the plastic covering the entire playfield made a material that will not get cloudy or scratched up when the ball races over it for a few years. I'm sure the team has thought about this. I'm glad there is a clear plastic over the entire playfield but I'm a little worried about how it will look after its gets played a lot. The monitor area will need to stay looking nice since looking through the protector is needed in this spot. Can it be waxed ? Should it not be waxed? How should it be cared for?
My Full Throttle seems fine so far. The plastic piece also seems like it could be popped out and replaced. I've never waxed it. That's all I can tell you.
Edit: I'm referring to the plastic overlay of the LCD playfield screen.
