3-In-One Anti-Seize Copper Grease protects metal components from corrosion, rust, water, heat and acid. This lubricant and anti-seize compound can withstand extreme temperatures, and has added graphite for even better lubrication across the entire temperature range. Once applied, a protective coating is formed which will not wash off or burn, therefore reducing metal-to-metal friction. Also assists with the assembly and future dismantling of threaded fastenings. 300ml.
