The dimples that people have been experiencing ( including some minor dimpling on my own pins ) have absolutely nothing to do with the thickness / hardness etc. of the clearcoat .
I recently pulled my Metallica apart for a clean and re-rubber . During that process I removed the magnet cores from both the Grave Marker area and Sparky . The tops of these magnet cores were both dimpled in exactly the same pattern as the playfields can be . I since machined them off nice and flat ready for re-install .
If the problem was something to do with the thickness / hardness / cure time of the clear coat , or even the softness of the plywood used for the playfield , then how would you explain the exact problem occurring on top of a metal magnet core which is not covered by clear coat and is made of steel .
I do have some photos but they are on the camera at work . I'll upload them once I get them .
