Quoted from Cdonnerusmc:

Ok so i finally unloaded my Ghostbusters premium from the portland retro gaming expo, my playfield has had a stamp of September 22 2016 and my machines Back box sticker is Oct 4 2016, again it had 0 plays before having a full playfield protector from Germany installed,shaker motor,and mirror blades and code update. It then went directly to the gaming expo where it was played on free play Friday night Saturday and Sunday. We noticed ghosting Friday night and by Saturday it was a lot worse. At the expo with the glass on it looked as if the air balls had dimpled the playfield through the protector but today I took the glass off and used novus 2 and the playfield along with the protector look brand new. I did a pretty detailed inspection and found 0 dimples at all. So i would highly recommend the playfield protector. As far as the ghosting goes, it's bad.. as you can see in my pictures provided. I ordered the cliffy shooter protector but sadly it did take a little longer to get here than i had hoped so I do have damage to my shooter lane. But honestly I expected it. Other than that the plastic on the top of the shooter lane broke off completely early Saturday morning again Its in the pictures. Not sure if everyone caught the side bu side comparison someone did on to machines using the same camera etc.. I can confirm that i have one of the less brilliant playfields mine looks washed out compared to the non ghosting playfields. At this point I honestly believe the number of plays has nothing to do with the ghosting issues Im guessing heat/humidity and cheap glue is the problem.. But this is just my opinion . Anyway hopefully this information has helped. I know a few people may still question this but i honestly have no reason to make things up I am being 100% honest and open about every issue i have had. If anyone needs or would loke more pictures please let me know.
