This is the third or forth time I've heard that Permatex Super 300, part # 80057 is getting hard to find. I bought a jar last year for Ol' Roy's water pump installation.

In reality, it is very easy to find. A quick search just now shows that it's available at NAPA, Advance Auto Parts, O'Reilly, ebay, and a wide variety of other well known and lesser known suppliers, as can be found on Permatex's website.
