Highly Effective, Reliable and Durable - Love This Stuff
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!)

Grease for Peace
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 and Thick
I like it.. is thick. Yes the brush is bent, and the brisels will be bent all over. So here is a Couple of tips. Don't use the included brush to apply onto what ever your coating. Cause if whatever your coating is a little dirty or rusty. It's going to be picked up and end up in the jar. Save some plastic bottle caps to put some of this paste in to use. Then use something else to apply it from the cap to your object. Qtip, piece of foam sponge, other paint brush, including small art brushes, popsicle stick, best thing ever...finger, maybe in a glove. This should help in keeping the rest clean.

Nice product but a bit on the expensive side
Works well wherever you may need a silicone paste. Adding this before friction type difficult installs is a must - seals/wire pulls etc… Goes a long way but the price is not what I remember and seems to have skyrocketed. I purchased this over 3M for that reason and it was still high.

Great Product, Usable for Tons of Applications
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.

This is great stuff to have around
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.

What you need for greasing brake pad contact points.
The product works as expected.. This is a good brand, and this product is important in keeping the metal on metal contact with car brakes (my purpose of application) lubes to make sure the brakes are able to easily slide and compress when you brake. This helps the brakes press evenly and keeps them from making noise when you brake. ChrisFix on Youtube is a great resource. You want to hit the ears on the brake pads and the metal clips, either your new or used ones ( make sure if its the old ones you clean them well before applying. Then also place some on the back of the brake pad where the Brake piston will press and touch the back of the brake pad. You dont need very much.. and make sure none gets on the pad itself or the rotor.. If it does.. use brake cleaner. (dont spray the cleaner on the actual pad either, on the rotor is fine.).. spray on a rag and wipe off the brake pad.
