Corroded sheet metal: Refresh or save

Hello, I have here a piece of sheet metal that is rusty (see pictures). In the middle below the rust has already eaten away something. Otherwise the piece is still stable. The part comes from a lawn mower, and it helps that the grass flies in the right direction. As you can see on picture 2, the part is put down in a kind of tab. Above the part is screwed in. So in practical terms the part still does its service. But how long… I think it is better now to I don’t have any practical experience with the subject at all. Who can give me an assessment of what options I have? Is it enough to grind it down here and bang on it with a strong paint and primer? Does it make sense to spat the little piece? Or to make it new at the same time? Body plate is quite cheap to buy. Can you shape such simple pieces yourself? Or would a body maker have to get there? Or how about a car body maker? em 3D printer? First make 3D scanners out of plastic. White jmd what the fun costs?
