I've got a Gottlieb Sys 1 Hulk that has 2 displays that were "repaired". They look great, but the glass is no longer stuck to the board. One had foam style double sided tape, but it made the display stick out too much and scratch the glass.

Now i have a new BG, and want a fix for these. I tried 3M "permanent" double sided tape (non-foam) and gravity won. Should I glue the glass down? And do they get too hot for say, hot melt glue? Super glue?

Also, curious how folks protect their nipples when the rubber is gone (insert jokes here).

Any advice would be welcome, Thanks!
