Permatex 81878-12PK Ultra Copper Maximum Temperature RTV Silicone Gasket Maker, 3 oz. (Pack of 12)

Works great.

It’s sealant, it works, still going strong after having it on for quite awhile (Used it for my headers and connecting to the exhaust)

I've used on exhaust and a wood stove. Great lasting product

Easy to use, works fine.

I used this for the various sealant requirements in my recent Mazda rotary engine rebuild. Rotor housing feet, front pulley bolt, oil pan. The color makes it stand out so when I got some squeeze-out from putting a little too much on the rotor feet, I could easily remove it before the oil pan was installed. The temperature range seems way overkill for this, but that's not a bad thing. While not specific to this RTV alone, make sure you clean the nozzle with a nail. Between uses you'll get boogers in your bead or a clog in the nozzle and nobody wants that.

Used this for a couple projects and it works great. The silicone has amazing adhesive-ness and temperature resistance that even after hours of continuous heat its not budging. That being said, the bottle it comes in has a weak back stich. A little too much pressure on trying to push out stuff and all of the bottle exploded out the back end. product is great, packaging is unfortantely poor.

Works great to seal V-Band connections on my downpipe. I was getting leaks from the V-Band with the metal to metal connection. I decided to try this RTV to seal the leaks. Initial impression, it’s working good. I don’t hear any exhaust leaks.

Product is as shown, works as it should.
