Best lube for dusty conditions?

[KnottedYet]

I've used White Lightning. It was dry and shed dust and sand well, but the chain ended up being awfully noisy. I only used it a couple times, and ended up tossing the bottle. Now I use Boeshield, which is also suupposed to be dry but work well in soggy wet conditions. So far it hasn't dried. I'm still waiting....

Edit: actually, I didn't TOSS the bottle, i gave it away.
