Polishing Predicta Plastic Screens

[Tony F]

Hello all. I was wondering what people are using to polish the plastic Philco Screen protectors ? I have some Novus #2 that I have been using on some of the radios that I have. I know that you are supposed to use progressively finer grits (Novus #1) which I don't have. Is there an automotive compound that would work just as well ? The Novus #2 seems to leave visible swirl marks in the plastic. Would some of the products that they use to bring back discolored headlights work ? I'd like to know what people are having the best luck with. And yes, hand polishing only. No power tools.
Thanks!!
Tony
