Has anyone tried Novus #2 plastic polish and scratch remover for polishing the myriad of plastics? Penn State now sells it for $5 - 6 a bottle. I've used it for years on acrylics and polycarbonates (non-turned stuff), and am now using it for Acrylic, and Tru-stone pens. It works great for me. I wet sand to 600 grit then use the Novus for a fantastic shine. I have gone to much finer grits before the novus. The difference is only that the novus works a bit faster if I went to 1500 - 2000 grit first. All in all, its less total time to quit at 600 and apply the novus. I apply it with lathe running at a relatively slow speed, keep it damp (with water), and continue til it shines better than a new car finish. Only takes about a minute.
I'm especially interested in comparing to the Meguiar's or other plastic polishes.
