Hi! I have Gottlieb Jumping Jack I am trying to get up and running. I was originally just going to clean it and get it working, but I am noticing that these inserts in particular are quite cupped. I think that they will affect the ball and probably wear pretty quickly if not addressed.

What should I do to make this game playable?

I have no experience clear coating, but have read about dropping clear into cupped inserts. Is this a good idea without clearing the whole playfield? I was thinking that I could remove the inserts and fill them with clear and then reinstall them. It seems like if I dropped the clear in while they were installed the sanding would be pretty tricky without clearing the whole playfield. How hard is it to remove inserts on a Gottlieb of this era?

I hope to get this game up and running soon and don't want it to be too big of a project, but I would hate to see it get excessively worn or play poorly.

What do you guys think? Any tips for me?

Level playfield and drip in some water thin super glue. It works.

Does the super glue possibly go cloudy over time with the ball traveling over the inserts? I was thinking of removing the inserts on my Firepower & filling them with clear coat then sanding them & reinstalling them, I also don't want to clear coat the whole playfield. This sounds like a great option.

I've never seen it get cloudy. Just apply and let cure in thin layers.

Is there a particular type of "water thin super glue" that is recommended?

You have to remove the inserts first. Then fill themuntil level, let dry completely and sand flat with 600 grit wet paper. Now polish on flat surface with novus and reinstall with gel super glue, done.
