Quoted from vid1900:BEFORE you send the blank one back, ask Jack if he is going to take care of you on your problem.
If he says yes, let him send you the populated playfield and then return him your bad playfield & the blank playfield in the same box.
If he says no, get your blank playfield clearcoated by a pro, then do your playfield swap - the game will look and play like a million bucks!
the problem I see with having a restorer clear it. IS that the ink and/or clear isn't grabbing to one of the previous layers. So someone adding more clear to an area where layer 3 was cleared on top of a non scuffed layer, wouldn't do much and layer 2-3 would still crack and release, regardless if more is on top.
