Looks great Mark.
Here is a link to the process of the playfields.Quite a bit more involved than just clearing.Definetly one of the more stress full jobs I have taken in because of all the unknowns at the begining .
Swapping inserts,stripping playfields,smoothing them, eliminating edges and brush marks,retouching etc.
