I find that Collinite 476S paste wax does better against stuff like that than any of my other LSPs, with the possible exception of *heavily* layered KSG.
Haven't tried out my FK1000P yet though, I sorta expect it to be great in this regard
also but that's just a guess.
As for products that are *not* all that great against such hazards, by beloved UPP isn't too hot. I get etching from bugs/birds quite readily with UPP, whereas the same stuff doesn't etch after *days on end* with 476S.
