Quoted from vid1900:First we need to understand that not all pinball playfields were created the same:
An old Classic Bally, Classic Stern, EM, or Williams Sys3-11 will have an Alcohol Soluble lacquer topcoat.
A Williams WPC or Modern Stern will have an automotive style clearcoat.
A modern reproduction playfield (like a Mirco or CPR) will have an automotive style clearcoat.
A professionally restored playfield will often have an automotive style clearcoat, although that is certainly not guaranteed.
-
So a cleaner that might be great for a Modern Stern, could actually damage a SS Bally.
A cleaner that would be OK for a perfect WPC, might damage a worn or planked WPC.
One size doe not fit all when it comes to cleaning a playfield.
-
We also need to remember that at least 5 different companies made the playfields for Bally/Stern/Williams.
Each may have had differences in the topcoat; thickness, chemical composition and the method of application all could vary.
Just because one person has used Novus#2 weekly for the past 25 years without sanding through the paint, does not necessarily mean that you will be able to have the same experience.
Do you understand correctly that for each model of the table, individual care is necessary? Where can I find care instructions for a specific model? Preferably not an expensive option.
