Hi Les,
I generally use Nino's method to clean the playfield (if it is black etc...) but you must make sure it is 100% clean before using Novus etc...You don't want to be rubbing dirt back into it.
I have recently used a Treasure-Cove kit on my Police Force playfield - which had dull mylar. It didn't make it look new, but I certainly got a reflection off it and is nice and smooth to touch. I generally give a light buff with canubra wax as well.
Don't forget to either replace the balls or tumble them and ensure the ball tracks etc.. are clean or it will just get dirty again.
Looking forward to the photos!
