Silicone contamination' to finishes, from spray furniture products should not be confused with using a drip needle bottle to treat flange bushings with Silicone / Naptha etc......The old "Silicone spreads out ..'creeps' like a pile of B B's', is an urban legend. Silicone: #1) displaces moisture#2) Is a lubricant...Both of these properties can be valuable for treating cloth flange bushings... Baldwin researched this extensively...
