I have a bunch of DC sae connectors for quick connection of my battery chargers to my less often used vehicles. Some are made of bright stainless, others are some metal with a corrosion resistant coating. The former look great, the later are showing some discoloration. I'd like to put something on them to keep the elements a bit further out and prevent corrosion.

My first thought was dielectric grease, but not sure if its the right thing. These connectors are just peeking out from underhood, but if the product separated and ran, it would be on my paint... Don't want that.

The product would need to prevent corrosion and preferably moisture from accessing the connections, not create a high resistance connection, and not run or bleed out.

Recommendations?

I would have a rag that has a bit of vaseline in it, that way you could quickly buff it on and it won't run.

Also, vaseline is pretty safe.

I thought that was exactly what di-grease was for. Just use a thin film and there should be no dripping. Just my .02

Spray them with Fluid Film which I think you've stated in the past that you have on hand. Not as messy as smearing grease everywhere.

I use dielectric grease when ever I remove a connector.

Same here!
ATMOF, my BIL uses Dielectric Grease on so many things that, he claims that he is finding more & more uses for it including brakes & brake hardware(never failed yet!). And he works in the heavy duty truck field.

I've always used dielectric grease on my plow motor and solenoid connections with great results. Like everyone else has said, that's what its designed for...any outside electrical connection to prevent corrosion.

Sorry to hijack, JHZR@ but there is so much confusion concerning dielectric grease; I'm confused myself. So how about a game? List all the applications you use dielectric grease on.

I have only used the tube stuff by placing a small amount on the end of a spark plug and a little on the inside of the boot. I also put a little on every electrical connector I have apart. How many uses am I missing?

I use it on all electronic connections in my vehicles. Thing is, open and exposed 12v battery charger connections aren't permanently connected, is a bit different, at least at my first glance.

Dielectric grease will work just as well as anything else.

The absolute authority on electrical contact greases is Nye Lubricants
http://www.nyelubricants.com/products/nyogel.shtml

Nyogel is recommended by GM and Ford to prevent fretting corrosion on electrical contacts.

This application (temporary el connections) is a great use for dilectric grease.

I use it for this very same purpose (for my Battery Tender connectors) as well as plugs such as the various trailers I use (RV, boat, utility).

It would have to be HOT (well above ambient temps) to make it run. And it wipes off clean with no residue typically.

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...

Here is one. I replaced a motherboard in a laptop and the connection with monitor was very poor no matter how many times I reattached the tiny plug. Remembering that DG fixed intermittent harness connection problem in my Subaru many years ago, I tried DG on the motherboard socket and it worked on the first try and works like a charm a yer later.

Could someone please tell me how exactly it works. If not, I will have to believe in miracles.
