Nice progress. Are those cupped double and triple bonus inserts?  The reason I ask is because my Flash has similar deformed inserts which need to be worked on. Do you use a clear resin to fill and level?

I have don this on a test pf and seemed to work ok. I removed the inserts, and swirled them on various grades of wet and dry sand paper until the were flat again. Then buff with novice etc and reinstall. Others might have differing opinions on this so wait before trying, but I think its the way to go. Obviously any decals would b removed in the sanding if present, but none in this case.
