RTV (Room Temperature Vulcanized) silicone gasketing material, designed for use in mechanical assemblies where the existence of higher, continuous temperatures up to 343C intermittent might exist. Upon curing, which occurs when the product is exposed to the moisture in air, the silicone forms a tough, waterproof seal on most surfaces. It will not shrink or crack, resists weathering, is sensor safe and is great for many automotive applications.

We used this high temp sealant on a generator exhaust in a building basement. This was an emergency breakdown repair & was critical to restoring power to the building. Product did a great job, recommend it to any exhaust join for a good deal.

Used this to seal up the rear diff on an 04 super duty after an oil change. 10,000km in and still not a drop. As long as the surfaces are gone over with a parts cleaner or something the product will stick to a vertical face, makes it nice and easy to line things up without worrying about drips.

Was easy to use and worked well following the directions. Meaning after applying the sealant I fit the item's bolts by hand and waited about an hour before tightening and it appeared to seal very well.
I was having a hard time cleaning the throttle body on my VE Commodore in the engine bay, so decided to take it off the intake manifold. The gasket was still in pretty good condition, but I decided to use some RTV just to be sure. Followed instructions, excellent product and great end result.Pic is result after about 2 weeks of regular use.
Easy to apply. Used for intake manifold gasket on my ATV. So far, so good. It works.
The product performed as stated and continues to meet the necessary requirement. Needed for use regarding an oven repair and has stood up to claims.
Used this to seal my head gaskets on an 06 wrx, only a thin line is needed to create a good seal. Only bad thing about it is the nozzle they give you is a bit wide.
Bought to fix annoying pin hole leak in water pump-to-engine gasket, to avoid having to take engine apart. Still working 2 weeks down the track with daily driving in hot weather...
Good product. Seals very well. Hi temp. Better than silicon.
