How not to !!! rear lower quarter panels

I've seen way worse.
That's not great for sure, but how do pop rivets, screen door mesh, and bondo sound?
Or my favorite, spray in insulating foam to fill the hole and bondo.
That's what i refer to as a ''stuff and f**k'' job.
Then there's ''gorilla hair'' stuffed into a hole and then bondoed up from there..............
