Here is what I use. It was purchased for my by a friend who used to repair pinball machines for a living. He picked mine up at Grainger. I EASILY get between 50 and 60 spins on my 1978 Space Odyssey EM and close to that on my 1980 Stern Flight 2000 with a good, firm shot.
I NEVER spray this directly onto my spinner parts. I usually just spray a decent amount onto a clean dry Q Tip and then work it all over the points where the spinner wires pass through the bracket. It lasts for a month or 2 and then I just spend another 5 minutes or less laying on some more.
My family and friends absolutely LOVE playing Space Odyssey because of that spinner shot and the ringing of the chimes when they hit it!
