Use Novus 2 on Data East/Sega playfields; avoid Wildcat products
Data East/Sega service bulletin 38a names Novus 2 as the playfield and ramp cleaner for these games, with Novus 3 for polishing metal. Do not use Wildcat cleaners, which attack the acrylic coating on most of these playfields and ramps. Millwax is discouraged because of its solvents; a paste wax such as Trewax is fine for waxing.
