Great Stuff to Have around.
I use this on my spark plug boots on all my vehicles. Good insulation & helps remove the boot when changing plugs. Also works on the threads of light bulbs so the bulb unscrews easly when changing it. Good price. A tube lasts forever it seems.

Simple, inexpensive insurance for electrical connections and spark plug boots
Permatex dielectric grease is one of those small garage items that makes a big difference long term. I’ve used this on spark plug boots, battery terminals, trailer connectors, and various automotive electrical connections, and it does exactly what it’s supposed to do. The consistency is smooth and easy to apply without being runny, and a little goes a long way. It creates a protective barrier that helps keep out moisture, dirt, and corrosion, especially in humid or salty environments. On spark plug boots, it helps prevent sticking and makes future removal much easier. On connectors, it reduces the chance of corrosion buildup and keeps contacts cleaner over time. The 3oz tube lasts quite a while since you only need a thin layer for proper coverage. For best results, apply a light coat rather than packing it in excessively, and make sure the metal contacts are clean before applying. Overall, this is an affordable and effective product to protect electrical components and extend the life of connections in both automotive and household applications.

Spark plug boot lube
Used on a new set of spark plug wires to keep the weld down. Also use it on plugs under the truck body to keep corrosion down. This is a lot of material if being used as intended. Works great. If this is your first time using this stuff remember that it just takes a dab, don't pack it full in there.

Grease
Worked flawlessly. This was the cost effective way to purchase (large size) it’s either a lifetime supply for me or I’ll lose it and have to buy another tube before I need it again.
