That overlay looks identical to one that was installed on my FG last fall.
Couple of things to be aware of, at least on my game it was not possible to perfectly align every insert with the overlay, so you may have to make some hard choices on how to approach it.
Here is the trashed PF before the overlay.
Here is the overlay applied.
Issues to note on the above pics...
Most of the inserts have a white ring around the top of the circle, this is in the overlay itself, must be due to improper alignment when they printed it? (See the green Clock Seconds inserts where it really stands out against the dark background).
The insert misalignment shows up in a few places, look at the red arrow at the top left of the lower pf picture, there is quite a gap of bare wood between the overlap black outline and the red arrow insert itself.
Also notice that the overlay is missing the darker red, almost burgandy shading from the original. It's almost as if the red in the overlay matches the highlight red color from the original. See the circled areas in the pic below of a stock playfield for where the missing second-shade of red is noticeable.
Even with the defects, it still much nicer than the original PF.
However, working with the restorer we decided to add touch-up paint to the overlay (after a thin layer of CC was applied) to a few areas to try to improve things a bit.
In the picture below you can see that the missing 2nd shade of red in the center star area was painted back in. It is subtle but really makes the center of the PF pop in comparison! It would be too complex to attempt to add it to all the areas it is missing, but I think it really makes a big difference for the center star.
The gap between the red arrow insert and the outline was filled with matching red paint, so it is far less noticeable now.
Some of the round inserts that had similar but much smaller gaps were filled in with black outlining, rather successfully IMHO. Here's before and after of the upper PF for example.
Once the touchups were completed additional layers of clear-coat where applied. The end-result is very good, far from perfect, but will make a very nice game - if I ever finish putting it back together...
