Its a product found in the auto section of your local canadian tire. Its made by a company called Permatex, which is the same company that make the product Ultraslick, super lube that is so revered around here.

There is a really good write up by Coach on here on how to use it.

But the short and long is that the stuf replaces your seals so there is no chance of it leaking. Think of it like adding cauk to your bath tub so it doent leak water everywhere.
