Anti-seize should be used on any bolt that is steel that is going to be threaded into aluminum. I also use it on any bolt or nut that is somewhat exposed to the weather that I forsee needing to be taken apart at a later date like say the axle nuts, swing arm nuts, cap nuts on the bottoms of the forks, etc.

I've had the same bottle of permatex anti-sieze for years. It has a high heat range and its usable on most metals.

 

I also like the permatex product. A container lasts forever. I have a large one with a brush in the lid, and I think that it will outlive me. I use anti-seize on spark plug threads and any steel (including stainless) fastener going into aluminum.

 

Should always use anti-seize compound on stainless steel fasteners. Otherwise galling will lock it forever.

 

Just always remember to use a wet torque if using anti seize.

 

I found three Permatex Anti-Seize Compounds each for different purposes.

Any recommendations?

For very dissimilar metals, go with the nickel based system. Also the best for stainless steel. The nickel is not as active as copper or aluminum.

Thank you for contacting us. For all these applications we recommend out Nickel Anti-Seize (77124). This is our highest temperature anti-seize making it great for exhaust applications and being as it is nickel-based it is non-reactive so works well with dissimilar metals.

Message: I am restoring a 1970 Honda CL-350 motorcycle and need an anti-seize compound for use on spark plugs, exhaust manifold bolts, and dissimilar metal fasteners (stainless steel, brass, copper, steel into aluminum). Is there one product can do it all well?

 

Hmm. Might interfere with my retirement plans. Trying to get the workshop all straightened out for that day.

 

The longer I pulled wrenches the less I liked anti seize. It's like that hot sauce commercial where the old lady says ...I put that **** on everything!

I have flushed out spark plug wells filled with it and have seen misfires due to some products being dielectric. BTW NGK does not recommend anti seize on it's spark plugs as they have a coating already on their threads.

A very small amount goes a very long way. If you have to use it for stainless to aluminum then I would suggest a stick style product and not the huge butt brush from the can.

Another trick to prevent both loosening from vibration and galling is to use a thin smear of silicone rtv on fasteners.
