I bought a kit that started with about a 150 grit disc, to a 200 grit disc, to 400 to 500 or so. Almost nothing. Then felt pad disc's using the Cerium powder. It's a ton of work. I have probably 3-4 hours in each lens.
With more patients they could likely get to be perfect.
But I'm happy enough for what I'm planning to do with them. Add light and hang on my deck.
In the end it was worth it. 4 more to go.
Although these not the exact before and after's, the ones that are done looked just like the scratched ones before I began.
