drew is right, the anti-sieze is better and lasts longer. The grease will seperate or cook out under heat. The anti-seize only uses the oil or grease as a carrier to congeal the compound for application. The silvery color is powdered aluminum (in permatex) which does not bond to steel thus providing a barrier between parts. Even after the grease or oil is cooked out under svere heat the part is still free. It is also available in Copper, Stainles steel, Nickel, etc from other brands. It is recomended by most all car manufacturers for use on lug studs, under carriage bolts, and e-brake components, among other places. I've been using it on our race bikes and 4x4s for decades and swear by the stuff.
