Quoted from sethbenjamin:
I just found this thread only *after* stripping down the playfield on a Sorcerer a friend of mine just bought. I'm doing all the rebuilding of pops and flippers, etc. for him. The game was dirty as hell, so I though, great, I'll bust out the Mill Wax as a first wave of cleaning.
Now I find out it's made with silicone and, if I understand correctly, any chance of a future clearcoat job has now been defeated.
So, moving on from that sad disappointment...I have been using Butcher's Wax on my games for a while, as it seems to offer lasting protection and really makes the games play super fast as well. Is there anything wrong with using it? I'll move on to Blitz when I need to buy more, but seeing as I'm constantly throwing money at these games, I'm inclined to use up the Butcher's that I have before investing $30 to try out a different wax. On the other hand, if it's really REALLY better or if Butcher's is somehow problematic, I'd welcome hearing about it.
Don't worry about silicone on the PF. There are removers now to get most of it off later on if necessary. Also additives for the clear coat to help with silicones. Its not perfect but its not the first time silicones have had to be addressed on auto paint.
As far as wax, Some of us are using this:
Collinite's 845 Insulator wax

ITs not too expensive, easy to apply and leaves no white residue.
