I've been curious and somewhat confused about when and where to use anti-sieze and dielectric grease. I know that anti-sieze makes it easier to take parts apart but are there places that you shouldn't use it (i.e. lug nuts, exhaust manifold bolts)? If you torque the fastener down to the proper setting is there any chance it will back out since it has less friction? Same with dielectric grease, on what electrical connections should it not be used? I know makes a better electrical connection and helps prevent corrosion due to dissimilar metals, but what about high current situations like on battery posts? Or shouldn't I worry about it and put it on all my electrical connections whenever I make a repair.
