Quoted from AlexSMendes:Well, I live about 15 km from the nearest beach, my game-room is next to my swiming pool, and yes, Rio has a humid climate.... But the odd thing is that only the balls of my TZ and TAF are rusting... That doesn't happen with my other 10 pins...
No disrespect, just found this a bit funny (First World Problem) ...
"I live so close to the beach in a wonderful tropical climate and my 10 pinballs are next to my swimming pool so it is causing a couple of my pinballs to corrode..."
