That is weird.
I would wax that in and see if it helps.

might be where someone trimmed off some mylar with a razor

If you are concerned you could seal it with thin CA glue. However it will then need wet sanding and polishing and might not be improved cosmetically. Personally, I'd just keep it clean and waxed.

Just spitballing here, but maybe use some clear fingernail polish to protect the area, then wax it.

It sounds/appears like damage to the clear coat. My first thought on repair would be light sanding followed by spot application of Varathane. The patch would then require sanding and polishing to match the surrounding clear. I've done things similar to this with good results.

I think no matter what you do you will either see the marks or the repair. I would pull the play field and get the whole thing touched up and cleared, that will fix it for sure.

It looks like knife cuts.

Most importantly, does impact ball play? I'm sure the flash picture makes this look worse than it is.

If you truly want it fixed, I have to agree with the ovfdfireman.

If its not that bad, and does not impact game play....I'd just wax it with a few coats, and wax it regurally.

Looks like scrapes from a screwdriver or similar tool and what appears to be a prior mylar line, so I'd say someone got a little aggressive when removing mylar. It also looks like some touchup paint was applied. The only way to really fix this is to send the playfield for proper touchup and clear, or live with it.

Dude, You ain't supposed to use real fish hooks to reel them in. Sell yer gear and get out the buffer.

Hit the area with some 600 or 800 grit sandpaper - lightly. Don't go through the art.

Get some Zap-a-Gap CA glue or a good thin-mix CA from a hobby shop, with a pipette applicator tip.

Apply the CA into the crevices and around the sanded area. Let dry completely for 24 hours. Don't worry about the rough top or cloudiness. Sand with 400 grit - USING SOMETHING UNIFORM AND LEVEL AS A SMALL SANDING BLOCK - after fully dry, using Novus 2 or spit, until the CA area is level with the surrounding area. Novus 2 and then wax.

Boy you guys are sure willing to spend a lot of time & money on a minor problem. The poster stated that it didn't look like it effected the artwork and wasn't as bad as it appears in the picture. Either wax it and live with it or do a spot clear and sand/polish. Yes you would probably still be able to detect the repair but you would have to be looking for it to see it and others wouldn't even notice.

gambit's solution is a viable option as well. I've seen it done but haven't used this method myself.

I would only strip and clear the entire playfield if there were other issues that needed to be addressed.

I think its normal...

It where they tried to hook the fish
