Quoted from flynnibus:
it is cured - it was sprayed many months ago. The formula they used is not resulting in a stiff finish resistant to compression like we are used to.
Cure is not the same thing as 'hard'. Cure means the chemical reaction has finished and the product is now stable.
I worked in a body shop when I was younger. I mixed/sprayed my share of paints and clearcoats. At the time, adding the right amount of hardener was critical. When I first saw this soft clearcoat phenomenon on a Stern playfield (IMDN, spring, 2018), my first thought was: Gee, lots of material was laid down - perhaps *too* much - but this is so soft that it's pooling at pressure points and whoever is shooting these PF's at Stern needs to add the right amount of hardener!
What irritates me about Stern's and JJP's responses so far is how dismissive they have been. They say a small group of fastidious ("obsessive"?) Pinsiders has been vocal about the issue but none of their distributors is reporting any complaints from any customers. Really? They also imply that the bad playfields are outliers and represent a tiny fraction of the production so far. Again, really? I would wager *all* of the JP2 PRO playfields were bathed in that inferior clearcoat. Heck, it would surprise me if the great majority of *all* playfields made by Stern or for Stern, beginning with IMDN, aren't likewise defective. The real "outliers" in this case are the few playfields that were sprayed sparingly, thus avoiding pooling - although not making them any harder, certainly.
It irks me that Stern dismisses buyers who complain about soft clearcoat as unreasonably demanding. They need to get in front of this - like, *now*! No more arrogant dodging. Own up and spell out your response plan, Stern and JJP!
