I debating on posting this thread but I think we as a community deserve to have transparency for these quite expensive products. I'm not trying to throw anyone under the bus but it seems like a centralized discussion is warranted to determine if there are wider spread issues or if there are simply isolated incidents.
My involvement here stems from my JJP POTC chipping around the narrow sling posts. These are Mirco produced playfields. When I posted a thread in the JJP forum about this issue there were many people who were in the same boat. The conclusions we have come to in that thread is that the narrow sling posts used had sharp edges on the bottom and this caused cutting in to the clear/art and eventually chipping of those pieces and bare wood exposed. This is combined with the very clear issue of a "soft" clear coat. Around any other posts and washers we have very apparent bunching up of the clear coat with a very real possibility that those areas will chip and crack as well. JJP has taken some responsibility here with a sort of "hidden" offer (JJP does not seem to announce these kinds of things anywhere) of a discounted playfield to those with chipping. They released a "kit" to add wider star posts to the slings with washers under them. The community devised and adopted a preventative measure that TNA owners came up with using a rubber washer under star posts.
Through this I've heard from other Mirco playfield owners that similar things have happened to them. I don't want to call anyone out, everyone can post their own experience and the community can decide.
POTC owners have contacted JJP over and over with many delayed or non-responses and very little acceptance of the issue. Several have also contacted Mirco directly or posted in related threads with no response. Not that Mirco is on the hook for JJP playfield issues, but it's their product in the end and their reputation.
It would be nice to hear both good and bad experiences with your own Mirco playfields, both from a pinball manufacturer installed product to a direct playfield purchase. I've read a lot of threads from a lot of different owners of different manufacturer's games and playfields who have reported issues. It's hard to take anything concrete away from all of these threads as there are many differing opinions as to what causes these issues, who is at fault, what expectations there should be for newer "environmentally friendly" methods of production, etc. I've read that Stern uses three different playfield manufacturers and some of their playfields have issues, maybe the Mirco ones? I know JJP had earlier issues with their Bader WOZ playfields (I had one of those) but their Mirco versions seem to have been much better, so why issues with DI and POTC? Some suggest methods have changed, some suggest Mirco has levels of quality which lead to issues.
Here are a few pictures of my POTC playfield issues and a link to the JJP related thread:

Dialed-In owners talk about their playfield chipping, I think those are Mirco too?

Maybe Mirco will chime in and clear the air give some input as to why these things might be happening.
