All this pooling talk has had me checking out the pinballs in my collection
I have pooling on the slingshot posts on both Batman 66 (2016 build) & Star Wars (2017 build)
Tonnes of games have been put on both machines, with no signs of chipping or wear
So make of that what you will, I never would have even noticed the pooling, had all this recent discussion not taken place
For the record, the pooling on both of my machines looks to be on par with the examples others have posted
