Di-electric grease on new electrical connections?

Beware of DeoxIT Power Booster:

I took a look at the liquid versions of DeoxIT products, and found some that had a better price, and were labeled "DeoxIT Power Booster" and contained in a needle applicator.  I couldn't find anything on the Caig site about "Power Booster" so I emailed Caig.  I got a reply that said that while "Power Booster" is indeed the same as DeoxIT D100L, any bottle labeled "Power Booster" is at least 20 years old, and that Caig could not guarantee the stuff was still much good. 

I was also told that the liquid version of their products has a shelf life of 3 years, and the spray versions, 4 years.  I can tell you for sure that my 10 year old spray can of D5 still works great, so I guess their shelf lives are aimed at when they'd like them to reach the customers.  That's only a guess though.

Be careful when spraying the De Oxit around rubber parts, I gave the computer plug a good dose and now I have trouble getting the plug to lock in, have to push VERY hard, I belive the rubber seal swelled

It may shrink back to normal with time.  Sometimes solvents do that to rubber.
