A factory DSM head gasket effectively has a silver paint like material on the outside. Ever tried cleaning up the HG surface after removing one of those gaskets? I firmly believe that OEM composite HG does not need any additional spray and it seems to be working just fine now.
I concur - and I used Copper Coat in the old days.
