I'm still thinking about using a SS steel rub rail system. So far, most of the ones I've found have been crazy expensive. Recently I've been thinking about using the SS insert for a taco system as a lone SS rub rail: http://greatlakesskipper.com/product/791_792-boat-rub-rail-rub-rail-inserts/7--stainless-steel-34-inch-x-8-ft-boat-gunnel-molding-rub-rail-insert.html Anyone else done this successfully? I also found these: http://www.brunnerent.com/Tools/Portfolio/frontend/item.asp?type=11&size=0&lngDisplay=0&jPageNumber=4&strMetaTag= extruded aluminium at a decent price. Anyone used aluminium?
