The inserts on my Lightning always had some warp to them but last week a ball actually got hung up behind a raised edge for the first time so okay, now I gotta tackle at least some of them, 20+ more years have made them progressively worse. Sunken in middle and many arrows are also warped upward at both ends.
Idea: I do not want to clearcoat the whole pf, but handle it per insert. Has anyone ever removed one and filled it with clear coat etc. *outside* of the pf trying something like this?
- strapping tape or wax paper or non-drying putty or something around the perimeter of the insert so there is a very very short temporary ‘dam’ of sorts around the top edge
- Eventually fill it so it also coats all the way up to the high spots a bit, not just the center
- then sand it perfectly flat if needed (full coat should prevent ink on it from being damaged) and spray a final layer on the top, clean up the sides and then shave the bottom of the insert a bit so I can level it with the pf?
I'm trying to come up with something that doesn't involve hammering or heating them because they are both sunken and have raised edges. Thanks!

I've leveled inserts by filling with UV clearcoat: apply enough to pool up (having perfectly leveled the playfield), then cure with UV lamp. It worked reasonably well.

But the best overall solution is to simply use a playfield protector if they make one for your game. I did that for Blackout and it made it super fast and super smooth!

On the arrows I don't think that would work though, since they are warped up vertically on the ends. It might fill in the center but edges would still be sticking up enough to hang a ball up. And not sure about applying a protector over those edges, seems like would be a bunch of peaks sticking up in the plastic.

Agreed.

You'd have to clamp them down and glue them from underneath first.

I have not tried this myself, but if I were removing any I would try this on one to see how it goes. I was told by the seller of a machine I picked up with a friend that had sagging inserts that he has had good results fixing this in other games by putting them in hot water and then leveling them.

I've done lots . Remove insert. Heat with hair dryer till warm enough so they bend with pressure but still hard to bend. Hold 30 sec to cool. Clean edges and insert hole. Reglue with super glue gel.

Done.

I did try the boiling method on one of the big blue arrows awhile back but didn't work that well for whatever reason. Plus it's large so a lot to go wrong while your trying to flatten it. Had trouble with heating with dryer and pressing a few inserts flat on couple other games too, where yeah the center is flattened but the sides start going goofy on me, it's always a little iffy. I wanted to find something more sure-fire where other than sanding the bottom I'm not coercing the inserts with heat but just a one-by-one leveling with clear thick enough to be able to refinish the top without damage to the art, then stick 'em back in. This week I'll try goofing around with some old sunken round inserts I have in a junk pf and see if this idea is a crap-out.

If you’re taking them out anyway and new are available I think replacing them is the way to go. It’s a fair amount of work no matter what.

One source for new inserts is Pinball Life. I think some of the triangles are unavailable, be sure and check before removing.
