Anyone familiar with corrosion-inhibiting compounds?

Anyone have any experience with MIL-L-87177 corrosion inhibiting compound for electrical interconnects? What about urea-thickened PFPE? Just wondering if there are any experts on corrosion inhibition for electrical interconnects(namely, fretting and galvanic).

I don't do mil-spec stuff very often, but we use products like "no-ox" for aluminum all the time. We don't use anything for copper or tinplated copper.

There is also a product called Penetrox for aluminum connections.

I've had good results with Burndy's Penetrox on lug-type connections, however, the problems I'm dealing with now are with pin & socket type connectors (i.e. circular, EPX, etc.) I need a product that will slow the effects of fretting, oxidative and/or galvanic corrosion in tin/gold interfaces. Obviously, the compound will only provide us an interim fix, but that is what we need at the moment. After digging around a bit, I've come across the two products that I've mentioned in my original post.

Clearly you know about the unreliability of tin-gold contact interfaces. You might call Nye Lube about their contact lubricants.

We have been evaluating the MIL-L-87177 CPC that the Air Force now recommends for all it's avionics/electrical connectors and the Navy has used for external mechanicals. The military test programs had amazing results. We are just getting test results back, but are seeing great results. Called Super-Corr B, from Lektrotech. Web address is
