Rebecca, tbh I've had exactly the same problems with krytox. Leaves a messy residue on the adjoining paintwork, especially if it's raining (almost always lol) and neither do I find it any longer lasting than gummi pfledge.
If I vaguely recall, the reason I used gummi pflege for this issue many years ago was on the recommendation of a BMW dealer. That's the stuff they were giving to 3-series coupe owners who were plagued with this issue.
