Quoted from javagrind888:
That's got to be one of the hardest cliffies I've ever seen to put on. I think I'll pass on this one and just check the mylar periodically.
It was a pain, but given what I've seen happen on Dialed In first hand, I definitely recommend the extra protection of metal. The clear on these mirco playfields can be brittle and irreversible damage (chip off PF art or cracks in the clear) can happen unexpectedly and without warning. I would not risk it.
It was really just more annoying to install than actually hard. I'd say about 45 minutes total. Take down the stand-up targets, get the ship out of the way, remove 4 nuts, lift the plastic a bit, take off 2 posts and one screw, wipe down the area with the activator, install the cliffy pieces, then reverse the process and put everything back on. Didn't like doing it, but would not recommend skipping it.
It would be a DREAM if JJP would continue working with Cliff like they eventually did for Dialed In and have a complete package of this level of protection was installed from the factory. If they involved him in the design process of the playfields, Cliff could also help them with making holes less damage-prone (angled beveling is not the answer). He has more experience with hole and playfield surface protection than anyone out there, I have no idea why Jack isn't tapping into that.
