Corrosion Inhibitor: Tef-Gel vs LanoCote vs White Lithium Grease

Corrosion Inhibitor: Tef-Gel vs LanoCote vs White Lithium Grease

(OP)
Hello,
I have a structure that requires 18-8 stainless steel bolts and 6061-T6 Al beams and channels to be isolated against galvanic corrosion. I have seen good reports on Tef-Gel ( http://www.tefgel.com)for this purpose, based on marine applications, and in searching the web, also found that Lanocote ( http://www.forespar.com/onlineCatalog/23-Lanocote.shtml )is used for similar marine applications. This leads me to believe that Lanocote could work as well to isolate the SS from the Al . Finally, with cost in mind, why couldn't I use a white lithium grease ( http://www.usseals.com/prod1.htm ) to isolate the SS from the Al? There are a few PTFE enhanced synthetic lithium greases ( DuPont: http://www.performancelubricant.dupont.com/dp_products_lithium.html , or LPS: http://www.lpslabs.com/Products/Greases/white_lithium.asp , and others... ) that seem to be a good choice. Is the PTFE adding anything to the corrosion protection compared to teh cheaper basic white l;ithium grease? Essentially, the Tef-Gel, Lanocote, and lithium greases are keeping moisture out of the dissimilar metal joint, so it seems that any of these 3 should perform equally well. My application is NOT a marine application. My application is for a roof structure in an (polluted) urban atmosphere. Thanks in advance.
