摘要

Surface finish has always been an important parameter for gasket and ring sealing. Head gaskets require a surface that is smooth and flat to cold seal and hold a lasting seal. The question is, "How Smooth?" When multi-layer steel (MLS) head gaskets became commonplace a number of years ago, there was a lot of concern that aftermarket surfacing procedures might not be able to reproduce the mirror-like finish that the vehicle manufacturers said was absolutely necessary to seal MLS head gaskets. The challenge was to duplicate the factory finish using out-dated equipment and methods that may or may not produce the desired results.
