Default Copper spray on head gaskets?

I read this in another thread about people coating the head gaskets with copper spray before fitting?

Supposed to help with seating on rundown and something about the copper acting to keep the heat transfer even around the mating surfaces...

Anyone else done or heard about this?

Copper gasket sealer has been around forever. Some use it some don't. It seems to be good stuff to me on metal gaskets.

I used it on two engines and they both are fine. I think moderation is the key. A light coating if fine but don't overdo it.

"copper spray" would have yielded you a nice thread about this from all of 2 or 3 weeks ago.

Bump from the dead...

Just wondering if people are using copper spray or not, and your impressions after long term use.
