Autozone (and probably some other auto stores) sell Brake Lube by CRC. I forget the actual name of the stuff. It comes in a little white bottle with a black label and red letters. There's a brush attached to the inside of the lid. It's really sticky black goo.
It's not cheap at around $10 for a tiny bottle, but it has a high moly content (and a few other good things) and won't fling off or melt like grease. I've been using it and so far, so good.
