ShinEtsu Silicone Grease, the best in the game!

[FTTSHO]

I recently came across a product called “ShinEtsu Silicone grease” on amazon. It seems like a product made for Hondas, might even be a Honda part number product. I read the reviews on Amazon and other forums and it seemed like the best product for rubber rejuvenating to keep them from cracking and becoming brittle overtime.


I bought it, and I tried applying it on an old and hard rubber gasket I had laying around in my toolbox. I applied it, and left it to sit for a couple hours. I came back and wiped off the access, and the rubber gasket feels like a brand new soft and pliable gasket. Completely “renewed” it. I’ve tried many “automotive” rubber conditioner products over the years, and non of them work this good.

I also applied the shinetsu grease on my 2001 blazers door weatherstripping. It was flat, and kind of stiff, but after applying shinetsu, I feels like a brand new weatherstripping, soft and pliable. It even made the weatherstripping bound back to shape a little bit, soft it’s not flat. Seems to seal better to the door now.

Just wanted to share my experience with shinetsu grease, and I think I will stick with this product.

If you’re looking for a product that can actually rejuvenate rubber very effectively, ShinEtsu is the one.

I plan on using this product on a lot of my old rubber seals and gaskets on my engine and the engine bay, because this product works amazing.

Great stuff. Tube came with my S2000, Honda OEM that also works on old Rovers, old Porsches and the occasional Piper door seal plus O rings, grommets!

I tried toyota red rubber grease for door seals and this shin etsu grease seems to do a better job and does dry up and get chalky unlike the red rubber grease

I haven't tried it on weatherstripping - does the white color clear up after a time?

I wonder if ShinEtsu silicone grease is any different than 3M, Mission, or dozens of others? SDS's are about worthless regarding ingredients.

Gummi Pflege Stift FTW !

Yes, shin etsu has a specific gravity tackyness and temperature range that is better suited for open air and door seals vs caliper pins.

Have both, both good, but I prefer the ShinEtsu, ages better and thicker consistency seems to seal wind whistles better.

Reminds me to go use my tube on my door seals. Have been doing this every 2 years or so and they stay perfect

The stuff is wonderful.

If you own a Toyota or Lexus sunroof, periodic application around the seal is required to prevent rattling.

The doors close tighter with it.

I had a supercab ford with the suicide back doors. Annual application silenced wind noise at those complex weatherstripped-mating surfaces.

Spoiler alert. If you add this to your maintenance program, you will notice which manufactures invest in better weatherstripping, and which ones do not. Lexus > Ford in that department. However, it was a disappointment that Lexus couldn’t build a rattle-free sunroof.

All thick paste silicone greases are worthwhile for the apps they are good at.

I bought another tub of Raybestos DBL-2T after my last tube of it ran out.

So many uses, just not so much metal on metal unless you have certain rubber formulations involved that can't tolerate petroleum based grease, then it's that or something castor oil based like Syl-glyde which has a much shorter service life. I don't want to imply there aren't other premium priced lubes for certain apps. Yeah, I'm not buying premium priced lubes for every vehicle and never regretted that choice.
