Had to use this since the surface between the 2 flat surfaces of the exhaust pieces where the gasket goes wasn't perfectly flat and the bolts didn't tighten it up enough for the gasket to work without leaking between the 2 pieces. Used this coating both sides of the exhaust flanges with the gasket in the middle, worked perfect and no more exhaust leak still years later.
