After hauling home dozens of project games over the last 20 years, today was a 1st. I picked up a Gottlieb Pro Football that was unmolested in a heated garage for the last 40 years. The flipper rubbers which are likely OE were broken and touching the PF. After a 1.5 hour drive home in 85 degree heat and sun they melted on the PF when I got home. I sure the PF glass increased the heat. Quite the mess.
I'm hoping either careful use of a heat gun or freeze spray will remove the residue without PF ink damage.
Never again. I will pull every flipper rubber in high heat.
