My last same-sized container anti-seize, standing at attention, lasting me 30 years (home use), so my children will finish this one.About it:It's silver in color, 8-oz. container (a bunch), -65F - 1600F, Anti-Seize, -Corrosion and -Galling; has Lid Brush; label indicates "Made in USA".Specific Use: Ease assembly and disassembly of hardware which experience extreme temperatures and/or corrosive conditions.I've used this routinely, and sparingly for it does not take much - just a light swipe on threads, mating surfaces etc.  Most of my last container went to lubricating boat and boat engine components for very good saltwater corrosion prevention.A general caution is: not apply to business end of sparkplug, O2 sensor etc (lightly on threads/sealing surface only) - else could impact component performance (never seen it happen lol).*UPDATE: I visited Permatex website - wished I'd done so earlier ... A summary:From Website Technical Data Sheets (TDS),This Permatex (80078) has ingredients of "aluminum, copper and graphite lubricants ... meets or exceed requirements of Mil Spec Mil-A-907E."Temperature Range: "-51F to 1600F"Flash: ">350F"TDS Applications: "Sparkplug threads, Exhaust & Engine Hardware, Brake Assemblies, Boilers, Ovens, Jet Engines and Turbines.", and does refer to a "Marine" use.Permatex Copper:  This may be a preferred product due to seemingly inherent do-all capability: Dielectric grease, anti-seize, anti-corrosion to include mating surfaces of dissimilar metals. Specific from TDS, " ... designed for stainless ... contains a high percentage of micro-fine copper flakes in a semi-synthetic, grease carrier and fortified with high quality rust and corrosion inhibitors ... provides good electrical conductivity ... meets Mil Spec A-907."Temperature Range: "-30F to 1800F"Flash: "300F"TDS Applications: "Sparkplug threads installed into aluminum heads, Exhaust & Engine hardware, Oxygen sensors, Knock sensors, Thermostat housing bolts, Fuel filter fittings, Battery cable connections."Permatex Nickel: Specific from TDS, "Nickel Anti-Seize was designed specifically for use on stainless steel or similar alloys ... use where copper contamination must be avoided, under conditions of extreme pressure and temperature and with stainless steel, titanium and nickel alloys ... contains tenacious metals, oils and graphite materials that cannot be burned away or removed by slow moving parts." Product description also refers "protection of mated dissimilar metals."Temperature Range:  "-65F to 2400F"Flash: "200F"TDS Applications: "Exhaust & Catalytic converter assemblies."Kyle
