Since we are moving to cable lubing/preservation I thought it would be a 
good time to surface my little test.

In April of 2008 I decided to test some of these cable lubricating products. 
I decided to take four lengths of the same wire rope that was used on my US 
Tower HDX572MDPL and coat them with these products and suspend them out in 
the back yard (I live on acreage in the country) and see how they weather 
the Florida environment.

I purchased the following products;

Fluid Film  a Rust & Corrosion preventive (its also a Penetrant & Lubricant) 
for wire rope and chains.
It is made by Eureka Chemical Co.

VitAlife 400 a wire rope lubricant, penetration lubrication protection.  It 
is made by the same company that makes the Crosby shackles and other tower 
rigging hardware. The company is The Crosby Group Inc.

Prelube 6 is a Preservative lubricant for wire rope and chain lubricant. 
Made by Grignard Co.

The last cable I suspended was just a length of plain wire rope from the 
same lengths with no protection added.

In two years I can only report that todate the cables with Fluid Film, and 
Prelube 6 have accumulated a lot of air particles as they are starting to 
discolor.  None of these cables show any signs of rusting yet, and the wire 
rope with VitAlife and the unprotected wire rope look pretty much as they 
did two years ago.

This test is ongoing and I have not yet reached any conclusions.  Keep in 
mind this is no professional test set up.  I just wanted to get an idea of 
how these above products would respond in my environment. I know they are 
not being stressed etc.  I am not sure how long I will let this run but the 
cables are not in my way and I will just let them hang and see what happens.
