 Don’t know if it would work on an iPad … but I got a nasty scratch on a Garmin watch & I “fixed” it with a protective cover (it’s still there … but at least you can’t see it ) 

 Toothpaste? https://www.iresq.com/expert-advice/fix-cracked-ipad-screen-toothpaste/ 

 Wanna do a test spot with toothpaste make sure it doesn't "dim" the screen. But it usually will get the job done 

 Hi, Ben.  
I'm back at it trying to finish my iris setup and a private Nostr Relay.  
Regarding your iPad screen scratch, I did the following search via Google, w/o the quotes.
You might want to do something similar via SearXNG?

"diy fix fluid for iPad screen scratch"

It returned several YouTube offerings.
Don't know if you've already reviewed them?
I hope it helps.

 I bet there's an app for it 

 Put a bandaid on it 😂 

 Not toothpaste 😜 

 Put a screen protector on it with some water on the scratch..😅
