Permatex is the only brand I trust for RTV Silicone. I've been using it for years, and I know it'll hold up every time! I always recommend it!
Second Time a Charm!

First tube of Ultra Grey Silicon was partially cured ( old stock ? ). Got another and was perfect. Used for water pump/timing cover and oil pan with success. I am a retired automotive technician 30 years turning wrenches. I agree with Permatex to use the Ultra Grey not Ultra Black for the repair that I did on my own vehicle.

This is the best gasket sealer on market I think it's amazing 👍👍
the strongest silicone made

i love Permatex RTV. anytime I need a sealant or binder that I know will hold strong I always look for this brand. After years in the auto mechanic business i have used this product thousands of times. Weather you are caulking a seam or reattaching a table Top.

This RTV was found using your search engine and I found the grey is best for high vibration applications, which is exactly what I needed for this project. Perfect find, thank you.

Permatex makes a very good product that's been around for decades. They make a variety of sealants that cover just about everything automotive and beyond. Walmart continues to be a great facilitater of this and many other products at great prices.
