RTV is "Room Temperature Vulcanizing" sealant. They are often, but I'm not sure if they are always, silicone based. These are sealants that apply as a stiff liquid/gel, then vulcanize to an inert rubbery consistency at room temperature. They have a nasty smell (cyanide?) when curing.
Permatex makes an RTV gasket sealer. I don't think there's anything really special about it, except that it comes with a fine tipped nozzle applicator and it is a very nice blue color.
It's the best stuff to have on hand for applications like the cam cover. Very good in situations where there is a rubber gasket that needs sealing.
For paper gaskets, it's not so good. Permatex makes a very nice, high tack, gooey brown sealant that never hardens and has a very nice sniff factor. Not quite up there with a good MarksAlot, but close...
