The old furler’s lower section had shipped a lot of sea salt over the years, and many of its fasteners refused to unscrew. So my second baby step was to squirt a little PB Blaster penetrating lubricant onto each nut, bolt and screw several times a day for a couple of days, meanwhile attending to other boat chores. This process reinforced my belief in using some kind of anti-seize or anti-corrosion goop on seagoing fasteners, especially in dissimilar metal assemblies. Given time and salty air, aluminum corrosion around stainless-steel screws will virtually weld them in place, making them difficult or impossible to take apart later. When I’d last reassembled this old furler base eight years ago, I had used Never-Seez. Yet it still took a couple of days of lubricating, and ultimately some sharp whacks with a 3-pound sledge on an impact driver, to break the tougher ones loose. Without any anti-seizing goop on the screws, I would have had to drill out every one, or else cut the headstay.
