Permatex Power Dielectric Tune Up Grease for Electrical Connections and Spark Plugs

I purchased this to use it on spark plug boots and battery terminals. it does a great job doing what it's supposed to do which is keep moisture out of electrical connections. Plus prevent corrosion of electrical connections. A little bit goes a long way so the larger tube will definitely last. Making this a great value compared to competitors smaller tubes.

if you have ever had to remove an old sparkplug wire that the boot was stuck on and has to be cut off you know the value of using this. It might not help this time but it sure will next time.

Really good product and terribly under used. When used properly this prevents most electrical problems related to moisture.

First time using. Chat said to use this after cleaning my car battery. Seems to help but haven't seen long term performance yet

this electrical grease is perfect for applying to any automotive 12v electrical connections. large tube probably last me a lifetime supply.

I've been using this stuff by this brand for ages. It's frequently marketed for use in cars in particular, but it works on anything where you're dealing with connections that can be damaged by oxidation. It's thick enough to stay in place, but thin enough that good connections essentially push it out of the way and it's extremely non-reactive (for example to battery acid, which is why it's most commonly used for cars.) But this stuff is fine for basically anything. You can put it on even things like headphone or speaker connectors. (A very thin layer though or it will make a mess. Don't slather it on like you do with car battery connectors.) It's not great at it, but it even can act a little bit like a lubricant on surfaces when very thinly applied so it's not sticky. They don't seem to have done anything to make the formula worse as of this time. Right now I can still absolutely recommend it for a lot of things.
