If you work in any industry that deals with the marine environment, you will eventually run across a product now call Aquashield.  This aqua colored grease is an industry standard for keeping metal parts from seizing due to salt water exposure. 

Yep, stuck with that on my hands all day.

But, it wasn't always called Aquashield.  Pulling out some old tubes from our lab shows that it was originally named Aqualube.

Unfortunately it does not stop the rust from discoloring the tube!

According to Aquashield's website; "Aqua Lube and AquaShield were both trade names for our waterproof grease. The two names were used to indicate use in different industries. We consolidated to one name in 2001."  Hmmm, so what other industry?  Why drop the name?  Let's do a quick Google Shopping Search to figure out what other product this could be.

    

Ahhhh, so THAT's what the 'many other uses' are......
