I'm sure "Diamond" is mentioned somewhere on my PARAGON but my VECTOR states "TUFF-COAT". Either way whatever the coating actually is it's sh*t. For a start it's water-soluble, hence the warning not to clean with water or soap solutions and why so many old Bally playfields suffer from extreme planking - any contact with water and the "clear-coat" literally washes off.
Sorry if this is a bit off-topic - I realise these are older machines from a different era.
