When it comes to electrical connections, is "Grease" really the word?

[Yachter Yat]

   So.....it appears I've got some cables coming in the mail.  These are the ones that go from the battery to the switch to the two breakers, that are located under one of my seat boxes. Additionally, I'm ordering two 100' rolls, each, of black and red Ancor #14 AWG that will serve for most of everything else, at least in the way of "under dash and accessory" purposes". 
   As with some of my past boats, this one will be kept garaged and undercover. Nonetheless, it will still be subjected to the saltwater environment. With that in mind, I'm wondering if it would necessarily be advisable to coat all of these new electrical connections with a little grease. Please note:  I'm only thinking a very, very light coating of grease.
   I've always been a fan of Johnson/Evinrude's grease. In fact, I've been using those products since about 1978 and have always been impressed at how these lubricants are so able to keep saltwater corrosion "at bay".
   I know of the existence of "dielectric grease", but I've never really used any son-called product. Interestingly, reading about its performance might lead someone to believe it's Johnson/Evinrude's product......packaged with a different label.
   I'm not really sure, at this point, but maybe the question I have is simply:  To grease, or not to grease.

I say yes. I'm not an expert on brands, I used a grey tube with matching grey cap that I bought at a local parts shop, don't recall the brand anyway.

I use Triple Guard and Fluid Film on everything and never have dealt with corrosion issues  .

Vaseline too, Neosporin in a pinch.The amount of grease on my boat and trailer would give Yat a panic attack.

Count me down for dielectric grease, T9 or Yamashield. There are other good products. Just don't accidentally get it in between two conductors that need continuity.

I use CorrosionX on all my connections. On my last boat I did a test. I coated half my new installation with CorrosionX and left the other half of the connections raw. After one year I had corrosion on the raw connections and no corrosion on the coated connections. I am confident that something is better than nothing here. Every time I touch my electrical system, its gets touched up with CorrosionX.

Nice to see this.  I just picked up a can at WM last weekend.  I was hoping that I had bought the right product.

According to the fine folks at Harbor Marine in Everett, they swear by Corrosion-X. I got a can of that spray as well and so far, only used it in my battery wires after cleaning/refastening to terminal posts.

This is good for battery terminals...

   Ordered a can of Corrosion X.  I'm not going to 'spray' that stuff, but rather, I'm thinking of putting it in a small paper cup and (once the electrical connections are tightened down), applying with a Q-tip.  Whaddaya think?

CRC has a dielectric grease spray that you can spray over your terminals and connections. A bit less messy than smearing a bunch of grease from a tube.

[Ghost]

Yes you should.  All of the things mentioned work, many work well.   

What I reach for, for electrical terminals specifically, is lanocote.  The one in a small tub.  Mine is about 25 years old and drying up to the point I need to replace it.  It's lanolin a very thick grease from wool that softens as your fingers warm it up.  It's sticky so as you coat something, it stays coated, basically seems like forever.  I just pulled apart a battery bank I put together ten years ago and it was still coated and sealed.  Easy to use product that leaves just the right amount of product behind.  I've used lots of things I'd use again, but I will search for that tub, just seems to work for me the best and I like smooging it on with my fingers and getting the non visual feedback that tells me that it got coated perfectly.
