I will be rewiring most, if not all, of my '66 using reproduction wiring harnesses soon.

I did a quick search on dielectric grease, so I understand that it is non-conductive. But, is it a good idea to use a little on all connections - interior and exterior/engine compartment - especially connections outside the interior?

How about on ground connections where a patch of bare metal is necessary for a good ground? Just smear a bit on there; and that should stem corrosion too, hopefully ...

Thanks a lot! :thumbsup:

Hi Dave.

If you can get the dielectric grease, it is always good to use it in plug type connections. avoid using it in high temp areas such as the headlight plugs. As for ground connections, if you start with a clean metal surface and make your ground connection under a bolt just paint over the top & it will seal it better than the grease. Might be a good idea to make sure everything works properly first before greasing your plug connections. It might get messy if you have a problem.

I put a dab in the female end of every connector on my car from front to back including everything under the dash and I've not had any issues.

x2. Even a tiny bit on light bulbs, never a problem replacing them down the road.

Thanks, Gentlemen - that's just the info I wanted. :thumbsup:

I got curious if there was such a thing as conductive grease and I found this stuff:

Sounds pretty good.

The "industrial" solution is NYK-77 "grease". Available anywhere truck lighting components are sold. I get it at the local NAPA.

* Corrosion preventive compound for electrical contacts, switches & junction boxes
* For periodic use with all electrical contact not using Fit 'N Forget connectors
* Available in a variety of sizes

You really don't want conductive grease on all electrical connections. You might give an alternate path for current to flow inadvertently.

A dielectric grease is an insulator that has no conductive properties but keep atmospheric gases from reacting with the contact metals (oxidation) on the connector or switch.

SO if high voltage is being used (spark plugs, MSD wires to the coil) this is not the stuff to use.

This is good for wire nuts though. Please note they sell a special version for different applications, the A version, E version etc.

Roy's post is the same stuff different distributor.

The NYK77 does not indicate that it is conductive (MSDS). Looks like it is a pure dielectric grease.

This is the spark plug stuff..

I suggest it's use on new connections. I would suggest the use of the No OX ID on older connections where some of the plating may have come off the brass.

If I had to have only one of the two I would have the Permatex as it is useful in all electrical applications.

One word of caution! If you leave this stuff laying about the garage it can get contaminated (meaning mildly conductive) from stuff just in the air. If you use contaminated grease on a spark plug boot you will get carbon tracking and loose a plug wire and perhaps a plug..

I have used the dielectric tune up grease on spark plug wire boots forever, and similar things, seems to work. Have always been shy about using it on routine connections because it is messy. Tried the "liquid electric tape" plastic stuff for awhile, and it seems better than not coating. Some stuff, especially on boats, seems to crud up anyway.
