Well I had the pleasure of speaking to John, the owner of the millwax company recently and I can tell you for a fact he uses this product on all his machines and has for years. Granted he is mainly an EM guy but does have a few SS machines, I believe he mentioned Elvira and the PM was his newest machine. Not disputing anything said here but John is a stand up guy and I doubt he would sell a product for pinball machines if he had any formal complaints of his product damaging someones machine.

I've met John, the owner of Millmax. He is a pinhead and would not sell a product that would harm a pin. He is a great guy, owns quite a few EMs. I belive vid is right the restorers hate Millwax, I have heard cfh voice his opinion on this matter.
