I was using Bag Balm, but it would a) not quite do the job and b) make me offended at the smell of myself after a ride (seriously, i had to roll the windows down in my car driving home it was so goddamn bad). Switched to assos creme and it does a better job with less offensive reek after the ride. I also use some body glide right on the sit bone area and that seems to have cut down the incidence by quite a bit (not completely gone, but much better)..
