I actually stole the idea from an electonics application. If you get scratches on your cell phone or mp3 screen, you can remove or at least lessen the noticeability of them with a soft cloth and brasso. I thought I would give it a try on an acrylic blank and sure enuogh, Wow it really shines it up. Seems to also leave a clear "protective" film which seems to resist dirt and grime. It works very well on crystal watch faces to remove fine scratches. If you turn synthetics, I'd sure give it a try. Does not take much, I put it on with lathe running, shut it off and buff it out with a soft cloth.
