Can I add that Day 1 Factory Mylar Protectors were developed for a reason. Diamond Plate was developed for a reason. It wasn’t just cosmetics as much as just keeping the paint readable for longer and keeping down the grooves that wear in the wood after the paint goes away. I guess I would call cratering any depression that can deflect a ball’s natural travel when a slow rolling ball rolls over it. This only should concern the player from a “it hit THAT crater right there and took a turn SDTM” viewpoint though. Casual players tend to take things in stride but competitive players take a frowning look a machine if they loose a ball due to some carny groove worn in the playfield, or some crater that sends the ball down an outlane unexpectedly. My FGy had dimples from only 250 plays due to a lot of “stuck ball on top of drop target bank - glass smacked by ball search” resets when I took it home from Expo. It was NIB and used for the Flip out tournament and so when a player got a ball hung on the drop bank, instead of tilting out a ball and knocking it loose, they just waited for the ball search to reset the bank, slam the glass and richochett back on the playfield. On site, I would expect paying players to do the same. Now, at home, I only let it happen if I am having a GC beating run and got a shot at bumping myself off the high score table, otherwise I shake it loose and live with the warnings and tilts. The dimpling on my FGy has not gotten worse since, so maybe a little tlc goes a long way.
