Which spray/lubrication/other are you using to protect electric connectors from mud and water

[prdicon]

Also in which parts should I use it?  

[Gwbarm]

I use dielectric grease, I have also used vasoline it seems to work OK, I just use the grease because that's what its made for. I use it on electrical connectors, battery terminals, light bulb sockets and spark plug boots.

I use petroleum jelly, which is pretty much vaseline but industrial. Smother electrical connectors, spark plug caps, leads and boots, battery terminals. It waterproofs things and prevents corrosion, and it never shrinks or hardens or gets leaks. My bikes go underwater.

Exposed metal and switches and things I sometimes spray with WD40 or an equivalent.

I've been using this as a dielectric for years as well as brake grease and pivot points and such. Trailer connections, spark plig boots. It's a lot cheaper and does the.same thing as dielectric grease.

Looks like good grease.

[Jim Denton]

For certain things I use it a lot. Not where actual grese is required though. 

[WillrogersII]

permatex dielectric grease, gray tube, does pretty good for me. 

[prdicon]

Where to apply it? There are to many connectors...

I have Honda foreman rubicon 2022 

[Ulfthednar]

Anywhere it might get wet.

Which is pretty well anywhere.

In the process of chasing down my connectors and doing the same.

Yes petroleum jelly,does wonders and cheaper than most

[frugalsob]

I use CRC or Permatex dielectric grease.

And like the others have said, any electrical component that gets wet.
