## Description

Product description

Review: Very happy with this purchase, I will buy again. - 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.
Review: 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!)

## Questions & Answers

**Q: Can i apply it to automatic window mechanism ?**
A: I've don it, worked great.

**Q: Would this do good to seal a usb port with a usb cord plugged in?**
A: Not sure why you need to seal a USB PORT but I see no reason it wouldnt keep it waterproofed.

**Q: Is this stuff good for polyureathane bushings**
A: Yes it is good for polyurethane bushings.....the lube they sell for the bushings is essentially rebranded dielectric grease too.

**Q: Has anyone tried this on fishing reel components?  Is it light enough?**
A: Definitely! I've been using it from 15 yrs or more... The main purpose, to seal the reel and protect screws from salt; for those that are not stainless I fill the hole with the grease to the top well, every where there is a screw head facing out. And all around the edge and bound surface of the gear cover, anywhere water can sip in! And in the gears, but I would mix it with other type to soften a bit for smooth reeling experience.

### ⭐⭐⭐⭐⭐ This is great stuff to have around
*by B***H on May 28, 2023*

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.
