Antiseize for exhaust studs

[BAHNST]

Hi, what is the best anti-seize for the exhaust studs-my understanding is Copper should be avoided with Aluminium (due to galvanic issues)

That leaves, Zinc, Nickel, and Aluminium bases..any thoughts/experience what works best?

I've been using this Ceramic Anti Seize for years. It works great. The first link gives all the info on it and the second one is just Amazon if you are looking at a place to buy it.

We've been using Bostik Never-Seez NSBT-8 Regular Grade for decades. Any time ferrous, whether plated or not, screws into aluminum; studs, case screws, spark plugs etc. If a torque is spec'd for the threaded fastener or item, take lubed threads into account & reduce torque accordingly. There are exceptions but they're few, such as when thread locker is spec'd.

Good Ridin'

Thanks for replies at least locally seems copper is out of formulations and replaced by Calcium oxide.....
133H is the Permatex "Silver Grade"
