It is surprisingly easy to find. It was actually much harder to find the identity of a brake fluid resistant sealant than it was to find it in a store. Lowe's has it, Autozone has it, Pep Boys has it... in fact, since I posted this thread, I've seen it just about everywhere. It has a kind of "As Seen on TV" type packaging that would make you think it was another Sham-Wow, Pocket Fisherman, or the like, but it's actually pretty powerful stuff. A word of caution, Methyl Ethyl Ketone (MEK) is not something you want to be working with every day, or getting on your skin, or smelling, or letting the kids use to build a fort with popsicle sticks. It's kind of like the open gear grease that I recommended in this thread Valve cover gasket alternatives to cork Use it with caution, don't breathe it, and try not to get it on your skin. BTW, that open gear grease that I reference is like magic for sealing valve covers against leaks but still allowing them to come off in a flash for setting the lash.

Patrick,
The MEK itself is not a sealant. It keeps the sealant viscous until it's applied and dried. Seal All could be filled with other solvents and have the same results. Once it's applied and dried, the MEK will have evaporated.
Like you said, be careful where you touch it. It will eat the oils off your skin very fast. Acetone is harmless compared to MEK.
Not that you didn't know that but your post sounded like, "Hey this is good stuff, it's MEK".

I understand -- I suppose they use it for a reason. Some folks take MEK very seriously. For instance, this thread: Use Of Mek As A Glue - The Fountain Pen Network
