Electric Bradley or Master built verticle smokers?

[GloryDayz]

I've always rubbed-down the inside with olive oil, and followed that with a very warm burn. In the case of a smoker, I'd runf it with very hard wood, and all the vents open so that it's a hot as you can make it, but a LOT of water (or beer) int he water pan. Do that for an few hours (moist smoke bellowing out as thick as possible), and the inside ought to be good and not taste like the factory.
