first off you need to take a small hammer to the holes, they look like air pockets the manufacturer left behind ( as usual) make the holes as big as THEY want to be, then if not to deep fill with light weight filler, but on the edges id use some glass resin and fiber fill to make it thick like a paste, unless it goes back far then id jus mat it, but the resin paste will make a cornor a whole lot harder then bondo crap lol
