I helped my dad replace the front brakes on his early 2000's taurus last weekend and the studs were caked in the silver stuff. I asked him if he put it on there, he said the dealer did when he had it in for some other repairs. So if a dealer did it, it must be ok!

and stud breaker. 

I always use anti seize on lug studs. And get this, I only torque them to the recommended limit 80 ft lbs. I know it seems low compared to those air wrench jockeys at most tire shops, but why would they give a shit if your stuck on the side of the trail and can't get your lugs off because their too tight. I've seen some shops use max torque on an air gun putting as much as 200 lbs on a lug nut. Then I've also seen tire techs at Costco use a torque wrench! at factory settings ! Go figure. Anti Seize rules  Screw " them. "
