Grease on dizzy cap points?

[Skunksmash]

This is probably a dumb question, but oh well. Ever considered putting some of that dielectric grease on the "points" of the inside of the distributor caps? What would happen? Main thing that kills caps in the long run, is those little... things corroding up and wearing out. I've taken it off a time or two, when it was time to do a tune up, and just sort of sanded the fuzz off the little points. Maybe someone knows what they're really called.

Anyway, this is just something that has crossed my mind in the past, although with no research on the subject, I've never done it. Could some kind of grease or something keep them from wearing out? Well, delay the process anyway.
