I have what might be a few noob questions. I've had my MMR (#947) for about a month now and it's gotten a fair amount of play with me and 4 kids around. I've noticed some scattered ball dimpling in the playfield (more than just a few). This is my second pin, as I've had a FT for about 12 years. I haven't noticed hardly any dimpling in the FT, in fact, I'm hard pressed to find any (but I do have some paint wear around the fish light inserts and boat ramps). In all fairness, the MMR lends itself to more launched balls so to speak with the trolls popping balls up.
So, my question... is this normal? Is this the same issue I'm seeing with Forum Posts referring to the Stern playfield issues? Or is that something else? I know it will never be glass smooth again based on my experience in the first month, but wondering if I should be worried. The dimples are quite small, maybe 1-1.5mm in diameter and the depth has to be quite small (I have no way of measuring it). And more importantly should I try to stop the progression at this point by installing a playfield protector? It's really only noticeable under very close inspection and unless you got a flashlight out with the proper angle, you most likely wouldn’t see the dimples anyway. But I'd like to prevent it getting worse if people think it will. I have no interest in clear coating because of the expertise involved and length of time. And I'm not sure it would protect from dimples anyway.
As I mentioned at the beginning of the post. I'm new to pinside, so if this is a general playfield issue with all pins I'm sorry. I tried to do some forum searches but couldn't find answers to my questions specifically with MMR, but like I said, maybe this is a more general issue.
