Novus is a semi-liquid (gel?) polisher which comes in a plastic squeeze bottle. How much elbow grease? Maybe ten minutes. It's a little like compounding a car finish, but this product is for plastics only. It has been around a while, but not very long as a retail product. It was actually developed by Western Electric (the phone company, WE made all the phones for all the Bell Companies back when the phone company furnished the phones and you just rented them). They used this product when they "refurbished" the phones so the one you got would look new. It is supposedly good also for polishing away the dull and weathered outside of automobile headlight covers but I cannot personally attest to that, although I intend to try it on my truck. It's not real cheap, I think I paid fourteen dollars a bottle for it on ebay and bought a bottle of each of the two finer grades. BTW, I don't think I've ever in a lifetime bragged on a product before. This stuff really works on plastic.
