## Description

Permatex Dielectric Tune-Up Grease protects electrical connections and wiring from salt, dirt and corrosion. Required for modern high energy ignition systems, dialectric grease extends the life of bulb sockets and prevents voltage leaks around any electrical connection. Also prevents spark plugs from fusing to boots. Suggested applications: marine and automotive electrical connections, spark plug boots, trailer hitches, and battery terminals.

Review: Perfect for Coil-On-Plug Boots - Used this on the boots for the spark plug coils on my 2019 Expedition (coil-on-plug setup), and it worked perfectly. The grease goes on clean, keeps the boots from sticking, and gives you that extra bit of protection against moisture and corrosion. Coils slid back on without a fight, and the next time I pull them, I won’t be dealing with torn boots or cooked-on rubber. Simple product, does what it’s supposed to do, and worth having in the toolbox.

## Questions & Answers

**Q: Can it be used for mechanical switchs on keyboard**
A: On a mechanical keyboard, you would only want to use this on the stabilizers where the metal bars come into contact with the housing. As for the switches themselves, you would want to use a much thinner lubricant. Suggestions are below:
Linear - Krytox 205g0 is a thicker lubricant that can help linears feel super smooth.
Tactile - Tribosys 3203 is thinner and provides good performance. Avoid lubing the legs, as these are responsible for the "bump" in tactile switches.
Clicky - Although you can lube clicky switches, nearly everyone recommends not doing so, as there is a high chance of losing some of what makes a clicky switch appealing to those who enjoy it.

**Q: How many uses do you get out if this tube?**
A: Depends on how it is used and for what. It will obviously last longer when used on small jobs vs. 
big jobs.

**Q: Is it a good product to use on ordinary home inside or flood lightbulbs? thanks**
A: Absolutely, it will keep bulbs from freezing into the sockets, it keeps oxidation out of any connections.

**Q: Can this be used with rubber O rings on flashlight?**
A: I am sure that it would not harm the o ring if you use it.

### ⭐⭐⭐⭐⭐ Works great

Excellent product

### ⭐⭐⭐⭐⭐ Easy to apply and worth the trouble
*by C***W on November 12, 2025*

Used this when putting in a new lawn‑mower battery and hooking up wires to the AC disconnect box — worked like a champ. It goes on easy, protects the terminals from corrosion, and gives me confidence that the connections are sealed up solid. A smart little investment for maintenance and DIY control‑panels alike. The lubricant goes on easily and works for a while. It comes out pretty thick but you only need to put a small film on your wires for it to work.
