I've heard it through the grapevine that many people have used and highly recommend Tegaderm for road-rash-type abrasion wounds. Not the same as an ointment but apparently protects the wound while allowing it to breathe and heal.
I personally don't like ointments for more than a short time (like a day) because I had a bad experience with neosporin suffocating a wound which ironically made it fester..
