for the article on crystal polishing I got to thinking about other methods to try. Since I also build plastic models of race cars I thought about what I use for sanding them, went to the tool box and hit on another method. You can get flexible sanding sticks ( they look somewhat like your wife's emory boards) in hobby stores in 3 grades. Since they are flexible you can lay the crystal face up on a work surface and sand with the various grades of sticks. This way you don't need to worry about ruining the bezel. I tried it out with a badly scratched crystal and the result was great. A final polish with crystal clear polish and it looks like new!
Hope this may be helpful . I am not savvy enough to add it to WiKi but if someone wants to try it and add it, that's fine by me.
