## Description

A blue tacky, aluminum complex grease using a highly refined base oil

Review: Reliable choice - I recently used the Sta-Lube SL3121 Water-Resistant Marine Grease to repack the wheel bearings on my boat trailer, and overall, I’m quite satisfied. The grease has a thick, tacky consistency and is notably water-resistant, which is crucial for marine applications. After several trips, the bearings continue to perform smoothly without any signs of water intrusion. However, I noticed that the grease is a bit more challenging to clean off compared to others I’ve used, likely due to its water-resistant properties. Despite this minor inconvenience, I believe it’s a reliable choice for protecting trailer bearings in wet conditions.
Review: Good product at reasonable price - I got this to lube bearings on a mini bike. It seems to work great. I can also use it on anything that needs grease that might get wet.

A: A teal color.almost like if you whipped the navy blue kind with air bubbles

A: I would think its not the right application to use it for. 
I like fluid film for something like this. Not sure if it will
hold up to chlorine though. I use it under my car as a rust
preventer.

A: No  this is not "non-toxic".
