Mission Automotive Silicone Dielectric Grease Paste - 8 Oz Dielectric Grease for Electrical Connectors and Spark Plug Protection - Waterproof Clear Silicone Paste Automotive Greases and Lubricants

Purchased a bottle of this dielectric grease 3 years ago and am finally getting towards the bottom of the bottle. I dabble in a lot of off-road hobbies from dirt biking to 4x4 wheeling in the Tacoma (pic of environments its exposed to below) so I wanted something that would reliably seal my connections that are subjected to mud, water and the resulting corrosion to reduce potential failures while out on the trails. This stuff has worked great and always stays where I apply it. Disconnecting electrical connections a year later and there is still evidence of grease in the connection. I also use it on my RC car electrical connections as well as when I do spark plugs (in the boot) on any vehicle I work on. I attribute the lack of electrical issues I've had to this stuff! If I had to say a downside I'd say its that the brush isn't the most fantastic and kind of starts fluffing out but that doesn't really matter anyways as the brush is usually too large for the applications I am using it on anyways. Highly recommend this, I'll be buying another bottle soon! (sucks that price has gone up $6 since Aug. 2020! $17 -> $23 but imo, still worth it!)

Pure silicone paste is noticeably high quality. Essential for sealing electrical repairs, lubricating calipers, and any type of rubber, as pure silicone paste is the only 100% reliable solution that won't damage the rubber.

Mission Automotive's Dielectric Grease/Silicone Paste/Waterproof Marine Grease is my go-to for various applications. It's a versatile, long-lasting solution for waterproofing and preventing corrosion in electrical connections. I've used it on my car, boat, and even around the house. The squeeze tube makes it easy to apply, and it works like a charm. Don't let bad connections ruin your day; this grease ensures smooth, moisture-resistant performance. It's a must-have for DIY enthusiasts and maintenance pros!

Nice, thick paste… good for a variety of things, like coating your battery terminals so they don’t oxidize. We use it for one critical need, however: we have a two-door fridge without a divider which we love, but the doors start to stick and not close or open easily when the seals dry out. So I spread some of this on the seals and contact points, then wipe it around and thin it with a paper towel soaked in silicon “oil.” The result is doors that open and close easily — like they did when the fridge was new (it’s about 15 years old now). It seems that manufacturers received a lot of complaints for this open design (meaning no middle bar), because I don’t see fridges like this available any more. But I love the wide open space with no divider… so nice for large items like pizzas or other dishes that are in large containers, etc., and without the middle divider there is sooo much more space. Not sure what I’ll do if it ever dies on us (actually it did once and I fixed it with a new capacitor). Anyway, this is great stuff… the brush on the lid gets wonky and bent, but still works okay.

This is an awesome product and use on my 3 cars. It's a bit pricy but worth it. Multiple uses too. This product has lasted quite some time and once I finish up the bottle I have, I will be buying another.

Love this product

The product is excellent, & customer service of the seller is outstanding. I have been using it on some outdoor flood lights, where a gasket on a vertical surface is very small & flexible, and tends to fall off before I can place the cover over it & drive some very small screws. I spread a small amount on the area where the gasket fits, which serves two purposes: One, it holds the gasket in place until I can drive the screws, and two, it ensures the cover will be waterproof. The consistency of this product is ideal for this use, and the applicator makes it easy to apply. I have seen instances on previous applications where the installer didn't notice that part of the gasket had moved outside the cover, making that a place where rain could enter. The cross section of the gasket is so small, it is hard to see if it is in place completely. This works like a charm for my application.

I bought a bottle of this stuff and I love it, this is not a sponsored review and it’s genuinely from my experience. So far I’ve used it on a few things including some o-rings, coolant hose connections (some people don’t recommend so I won’t either), and spark plug boots. When I get to that point on my sitting car I wanna use it on the caliper pins as well. You can use it for a ton of different things and some of them are listed on the bottle if you’re wondering if it’ll work for it. It’s a lubricant and it’s good for electrical applications. It is kind of expensive but for me it’s worth it, again not sponsored.

Best thing on the market for getting your line and low voltage to work properly

Exactly as described

Fantastic

This dielectric paste (grease) a must-have for all marine and automotive wiring and connections. I have used this extensively on all of my boats' connections: sounders plotters, radios, electric downriggers, alarms, bilge pumps, internal and external lighting battery connections. Just apply a little at a time it goes a long way into protection. Using this will make all of your electrical equipment run better and last longer.
