Hmmm...that's not consistant with the message below sent to distributors from Stern (see bold text).
You have told me that some customers are concerned about dimples in the game playfields.
As noted on the cover of our game manuals, each pinball machine has unique characteristics that make it a one of a kind American made product. Each machine will have variations in appearance resulting from differences in the machine’s particular wood parts, individual silk screened art and mechanical assemblies.
The wood utilized by us and our former competitors for playfields over the last decades has been made to the same specifications, as has the “hardcoat” coating. The routing, sanding, finishing, etc., processes utilized to manufacture playfields over those decades have not changed.
Some dimpling of playfields is to be expected. I have seen this throughout my pinball career. A steel ball is harder than wood and its coating, and the softer materials will always yield. The coating was developed a few decades ago to protect the playfield from the ball wearing through the art to bare wood as was typical in older games. The coating was not developed to prevent dimpling. Although referred to as a “hardcoat”, the coating actually was developed to be flexible enough to flex with the playfield as the wood expands and contracts with changes in the humidity and wood moisture content.
Further, too hard a coating will crack during playfield assembly at the point of part insertion and rollover slot fluting. With the thicker application as desired for collector models, the coating itself will show more dimples, and the desired higher gloss of the coating makes dimples more visible. The layout of some game designs may result in more dimples in a particular area, and the art design of some playfield areas may make dimples more noticeable.
My experience has shown over time the surface will level with game play, reducing dimple visibility.
I refer you to discussions on the Pinside forum. I am attaching addresses for posts relative to a Funhouse and an original Medieval Madness, confirming that playfields will dimple but level with play.

Thank you for bringing your customers’ concern to my attention. Please assure your customers that initial dimpling is normal in pinball and is within our quality parameters.
