Normally, you can play a PRS for 30years on the road and have nothing more than some dents in the finish on the back. You can't call it buckle rash with the bare wood dotted by some finish still clinging on. I does depend on the owner too as to whether there is some dents around the edge of the body and headstock but you have to get close to see that but until you do, it looks basically new.
Unless its not the typical finish, I really don't understand how it could possibly slip through. Its not just the sprayers - who should of done a finish coat after the guitar was given its serial number on the headstock, but then the bufferers should have noticed and returned it to the sprayers because they couldn't buff that. then someone would have had the guitar to put all the hardware on - drilling the holes for the tuner screws, pick up rings etc - they surely would have noticed and, if its as soft as you say, would probably of damaged the finish just by handling it to put the hardware on. These aren't the last QC as I believe it has a second check, set-up and play to ensure everything is working before it goes to the final QC check - the people that put them in the case, sign the hang tag making sure everything that should be in the case is there and ensure everything is perfect to ship.
Of all things, I do think that something like that, with a standard Finish (not Nitro or Satin), is incredibly unlikely to slip through all those steps without being picked up somewhere along the chain...
