I think you might have misinterpreted Gaucho's question. It seemed to me that she wasn't necessarily questioning the efficacy of dipping so much as the statement that it penetrates deeply into the wood making it better than other treatments. Which mostly likely it does not penetrate deeply into wood. I've seen studies in boatbuilding journals about the penetrating depth of epoxies. Granted these aren't molten wax/rosin mixtures, but I think there is some value in the comparison. Keep in mind they are talking about high quality epoxies like system 3 or west system. These epoxies are very thin unless you choose to thicken them with a filling agent. The studies found that much like other coatings the epoxies fail to penetrate very deeply into the wood(we're talking minuscule depths). Which was a common notion as to why they were so much stronger than other bonding agents. So it is unlikely that wax/rosin gets it's longevity of performance from it's depth of penetration. That doesn't mean it doesn't work or isn't worth it. Just that the "common sense" explanation for how/why it works isn't valid. IMO people have a right to question the validity or source of imformation from someone who posted a statement, without being told to google it. Not that i"m against people doing there own research because I think they should, but if we make a statement without attributing it to another source it is ours to defend.
