Filling gouged plexiglass with what?

I have an arcade control panel that has art that’s bonded to the plexiglass and now it’s gouged from improper storage. Anyone ever filled gouged plexiglass with an epoxy of some sort? I’m thinking windshield repair epoxy and then just cutting and buffing the whole panel. Any recommendations?

How deep is it? Too deep for Novus #3?

I pretty certain it’s beyond Novus #3. Kinda looks like it was shot with a bb gun kind of damage. Just organized my garage, so now i’m ready to get it out of storage. I’ll take pics later today.
