Lynn, I think it's definitely worth a shot. Use pure cerium oxide powder and cotton swabs dampened in water. I worked in small circles, always moving around the surface and periodically reversing, trying to cover the lens as evenly as possible. Use as little pressure as possible. The swaged-in edges are the hardest to get at, and there's a tendency to overwork the center - just be methodical and you'll be fine.
The paste will dry quickly; I found it was best to work with small amounts of paste only until it dried, then go over it with a clean wet swab to take off the dried material, then start over with fresh cerium oxide. It's tedious, but you will see results relatively quickly. Good luck!
thanks for the explanatory notes!
