Wait till we get ours to compare Nick, does not sound good though, I would have expected the inserts should be spot on flush with the playfield....
Just re-read my comments, and realised might not have been clear - the inserts are perfectly flush, what I mean is the clear can be seen to have sunk at the join between the inserts and the playfield, ie you can see a tiny ring where the clear has not filled the join. This would disappear for example by a clear, then sanding, then clear (X number of times) as each sanding leaves the ring still filled, so after sufficient coats, the join becomes perfectly flush.
Does this make sense?
