I am in need of a waterproof grease. Its only purpose is to provide a barrier to the intrusion of water.
The application is Honda ATV brake hubs. The hubs are designed to use grease in grooves around and within circular flexible seals that rotate with the brake hub and are in contact with a metal backing plate. The grease barrier between the hub and the backing plate is the only thing that keeps the water out of the brakes.

Lithium marine greases do not last one ride if I have to ford much water. Since I will have to order the grease I was wondering if anyone could comment on the waterproof characteristics of the aluminum vs calcium complex greases or which one would be best for this application.

IIRC
calcium sulfonate type greases are widely compatible and handle "severe" water conditions well.

I am not a grease expert but I would have to believe any Marine grease would work because boat trailers are submerged in water.

How about a silicone grease? I was having issues with Super-Lube getting washed out of my polyurethane bushings when I used to DD my Mustang. Switched to Jet-Lube NLGI #3 silicone grease and it lasts multiple times longer between greasings.

Aluminum greases are great when immersed in salt water as sodium will not really break the bonds of the detergent molecules to the aluminum ions. But calcium greases will do well in fresh water. So either should do you fine

I recommend a sliicone grease like Krytox

BMW motorcycles of the oilhead vintage use needle bearings on pivot points for the final drive that are very poorly water sealed. I have replaced them several times. Last time, I washed out the bearing and packed thoroughly with silicone grease and then on assembly but in a barrier of more silicone grease. Never had a problem again.

Krytox is not a silicone, that is the point of the material.

There are fluorosilicone greases such as Molykote 3451 which cost a whole lot less than Krytox.

Mystic Marine Grease uses an anhydrous calcium system.


If you want the job done right......do it yourself.

I always used Bel Ray on the dirt bikes. I believe it was an aluminum compound and it was commonly available at motorcycle shops.

Bel-Ray Waterproof grease is an aluminum complex grease modified with barium complex grease. It is probably one of the most water resistant greases available and will act as an excellent seal against infiltration. It is available in a lot of motorcycle and powersports shops in small tubs.
