I would not spray it on. As the alternator heats up it will liquify and possibly dribble into the armature. If any gets on the brushes a film will build up on the commutator. This will solidify as it cools and the alternator wont work as soft seal is a insulator.

PS. We use this stuff all the time at work because of it's insulating properties.
x2.... I totally agree with Ian ie, don't do it Doc...! Water simply splashing on your alternator won't hurt it, in fact it'll probably help it's efficiency by cooling it more effectively than the normal engine bay hot air flow circulation. It will quickly dry out, even if it's temporarily fully submerged, such as during a river crossing. The only thing I would personally do to allay any possible concerns after just such an event though, would be to check that it wasn't left chockers full of mud, and if so, a simple hose out with a strong jet of clean water from a household hose would be all that you'd need to do. They are really not that "fragile" a device.
