Quoted from dnapac:One more question. So, we have run into this problem, and the companies don't seem to be very innovating with fixes on site. Has anyone tried to fix a ghosting insert? One way I have thought of it using a fine needle and injected more clearcoat directly into the bubble. The small puncture could be lightly sanded and polished so almost not visible...just a thought.
We used UV resin with a very fine needle. You need 2 needles, one to inject and one to purge. Injected the resin and UV cured. Works, but we should not be doing this on any new machine. We got the info from a thread on Pinside. We currently have 8 machines and the only machine that had ghosting was GBLE. We attempted the fix the day before we were due to get our replacement playfield.
