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?

The scope of this project is not to spend too much $ on the work. Initially, it was a case of "getting it going", but it needed so much work that it became a full recondition. If I was restoring the game, some inserts would be removed and flattened using 240, 400, 800, 1200 Grit Wet / Dry and then Novus 2. This game was a few inserts that have art on them, and therefore more time needs to be spent if all were to be removed and levelled.

I don't use the clear resin solution. I always remove and flatten.
