Quoted from MustangPaul:Well then can people feel them sinking.
Yes, can feel and see. I measured the plywood at 1/2" and inserts are 1/4" thick around the edges. They cut a lip into the playfields and glued the inserts to the lip. If there was something on the inserts makeing clear not stick it wouldnt be starting on the edges. Since the ghosting starts on the edges and works inward its got to be the way there glueing or installing the inserts in my opinion. The glue or wood edge has to be compressing some cause the inserts are tight and not loose. Similar to how the shooter lanes are compressing and the clear is separating from the wood. The clearcoat can only bend so far before it lifts off whatever its applied to wood or inserts.
