Can I add a coating or anti-seize to my gaskets?

A…While we prefer that gaskets be installed with only the factory-applied anti-stick, experience shows that additional anti-stick is helpful in some situations, such as areas where flanges cannot be separated easily. Coatings should be as light as possible. Dry powders are strongly recommended over pastes and grease-type compounds, which can drastically reduce the crush strength and blowout resistance of the gasket. Additionally, grease or paste type materials may deteriorate or dissolve in service, leaving a possible leak path across the gasket.
