I'm kinda pissed at my LHS guys, I'm good friends with them so not big deal, but called up asking if they had ball diff grease specifically, said they did, when I got there they tried to sell me some HPI heavy duty gear grease, or some marine grease. Ended up buying the HPI anyway and going to see if it's much diffrent that what I already had.

I know it's hard to describe, but what makes the ball grease different front the regular stuff? Is it thinner or thicker or just less slick than normal?
