I had a bad head gasket and I just recently replaced it. Prior to installing the head gasket I sprayed it with two light coats of Permatex copper coat. I took it out last week for a couple of trail rides and it ran just fine, no issues with it like I had when the head gasket went bad. I was in Moab this last weekend and popped off my radiator cap and saw some of the copper coat spray on the rubber seal of my radiator cap. My question is-Is this normal and nothing to worry about? Has anyone else who used the copper coat seen this? Like I said the bike is running totally fine and doesn't have any issues like it did before. Perhaps the copper coat is coming off the head gasket from the areas where coolant is running through the gasket and accumulating on the radiator cap??
