Q&A: Tef-Gel Versus Never-Seez

Question: I am intrigued by your high praise for Tef-Gel. I have not heard of it before, and in the past I have used ‘anti-seize’ for mooring shackles and installing stainless steel fasteners in aluminum. I am curious about your experience with ‘anti-seize’ versus Tef-Gel. In addition, I have had good luck using BP Blaster to loosen s/s fasteners in aluminum when there is some corrosion. What works for you when s/s fasteners are being stubborn?

Answer: I can’t say that I have really done any comparison between Tef-Gel and Never-Seez® (I assume you are talking of Never-Seez or one of its close cousins). We carry both on the boat and we tend to use the former on areas where stainless steel and aluminum meet and the latter for steel on steel interfaces. Both are good products and we have never had trouble removing a fastening that was treated with either.

As far as BP Blaster is concerned, I have used it a couple of times but not found it any better than anything else for loosening a seized fastening. In most cases, I have found that if a stainless steel fastening was installed dry into aluminum and is well and truly seized, about the only thing that will shift it without ringing off the fastening is heat. To that end we carry a MAPP gas (burns much hotter than propane) torch, although I have to say that, as we have owned the boat since 1991, have disassembled most everything on her in that time, and are scrupulous about always treating screws, it is not much of an issue anymore.
