After shearing the head off a screw still in my bike I've decided to get proper anti-seize. I have an aluminum frame and stainless steel screws. I've heard that zinc based anti-seize is better for aluminum-steel connections. I've also heard though that the additives in the compound only really make a difference at high temperatures which are not reached on a bike.
Aluminum based anti-seize is often 4-5 times cheaper than zinc based anti-seize and much more common. Is there really any performance difference between the two in this case? Alternatively, would a "marine-grade" anti-seize without metal additives be better than either of these cases?
