LOCTITE LB 8023 Marine Grade Anti-Seize is recommended for salt water use w/ stainless and titanium.

LOCTITE® LB 8023™ Marine Grade Anti-Seize is a metal-free formulation to protect assemblies exposed directly or indirectly to fresh and salt water, Loctite Marine Grade Anti-Seize works especially well in high humidity conditions. It has excellent lubricity, superior water wash-out and water spray resistance, and prevents galvanic corrosion. Protects in temperatures from -20°F to 2400°F (-29°C to 1315C).


It's basically calcium + boron oxide in grease + graphite; keep off of skin and eyes.

Sounds effective but horrid. I still have lots of lanolin left.

You may find adding some graphite to the lanolin works well; traditional
steamboat anti-seize is cylinder oil thickened with graphite - but they
never used stainless as it really didn't exist then.

Yes and I'm sure that graphite smeared about on my sails would excite no comment whatsoever from Barbara!

Stainless can do slightly on things, and in certain conditions with the wrong grade (like cheap stainless and salt water) will also corrode as well as anything else out there. That said, in my limited experience of using it which mainly involves some oil/grease/copperslip if its going to be outside I have yet to have an issue.

Ditto zinc plated, of the various mass of grades, which can again also corrode but often also includes phosphate wash or the like. At work they use zinc and yellow passivated nuts and bolts which are great, if in the process of being phased out on environmental grounds.

All depends on the application however, basically our whole engine is just unfinished mild or machine steel, and I have never had an issue with anything failing to come undone, but then it gets plenty steam oil over it all the time and lives in an engine room which even over winter is far from being outside.
