Novus #2 works great for cleaning and polishing plastic items including
ramps, playfield posts, plastic light shields, and so on. Novus #3 is a
grittier polish that removes deep scratches. #3 must be followed by #2 for
the repair to be perfect. Note that Novus also removes scratches from CDs!
Novus products are available from most pinball parts suppliers as well as
motorcycle shops, and plastic suppliers.
