Thanks Bob,

I’m new to the game and haven’t used most of these products.  When I was a teen in the 70s the Indian Head gasket sealer was the only thing I used regularly for automotive gaskets.  Then they came out with the RTV silicone products.  I don’t know if I did something wrong, but back then I used the RTV on oil pans and valve covers with mixed results.  Now, there’s a huge variety of RTV products and I had lots of success with them when I owned a 1972, 120 Hp OMC sterndrive.  The high heat version worked well on the exhaust manifold gasket and saved me a trip to the machine shop.

I saw on the Three Bond website that they too have an anaerobic sealer that’s intended for metal to metal flanges. I thought the sales rep would’ve steered me that way but he ghosted me.
