Quoted from GPS:Hello All
Want to go ahead and clear that back of the glass for another game I acquired. If I'm not mistaken some have said, including force flow I think, that they do not try and seal off the display windows, rather just clear the whole thing as the clear will not be seen. I always tried to protect the windows but maybe a waste of time. Just trying to confirm here.
Thank you
George
I have the same cardboard display covers I've been using on Bally SS and Gottlieb EM's glasses for 20 years. I use scrap metal 3/8" sockets to hold them in place when clearing a BG. All looked great. That's just me.
