I noticed a post that mentioned Stenner Aquashield Grease. I recently bought a stenner (fixed displacement pump) setup and will be installing it soon. I noticed the only place the fixed pump needs Aquashield is on the shaft tip that centers on the end cover. I didn't order any grease, as I didn't realize it was needed at the time...I still have a while before I would need it, but looking at it got me wondering- is it just white lithium grease packaged under the Aquashield name?
