Patrick - You, perhaps inadvertently, transposed my question. I wasn't suggesting alcohol-water over naphtha (sorry for previous mis-spelling), but the other way round. As best as I can tell, naphtha does not contain water and is a solvent, thus, I would think it would clean without shrinking. As far as the manufacturer's suggestions, isn't this a similar problem for which Wurlitzer proposed using mineral oil and silicone? And of course, who can forget the manufacturers (Baldwin) suggestion as to how to deal with black butt corfam, or whatever)? My fairly specific question with regard to shrinking is the effectiveness of controlling both the amount of water in the mix (as per previous posts) and the amount of shrinking that occurs. Why (I'm about to do that think that Ron hates: speculate) would you assume, or find, that shrinking positively addresses a center that is waxified?
