Thanks for the advice and the link, David. This is a new wheel and is nice and tight, but what you are saying makes perfect sense. For a dry, slightly loose wheel, would the preferred method be to soak in linseed oil, then apply the epoxy, thereby trapping it inside? I'm not a wood person, so I've always wondered what would be the effect if, what I would consider contamination, were soaked into the wood. You'd never get away with stuff like that on metal. Wood is a mysterious thing to me.
