Review on Permatex 77124 Nickel Anti Seize Lubricant by Jorge Maertz

This nickel anti-seize replaces a bottle left at a friend's house. This is used any time a nut, bolt or screw is replaced or reinstalled on any of my vehicles. Note that this is rated for 2400 degrees Fahrenheit and is NOT safe for O2 sensors. It can be used on exhaust manifold bolts, exhaust system bolts, muffler clamps and exhaust pipe assemblies where the anti-seize properties of copper must be avoided.
