Is it good or bad to use copper spray sealant on your headgasket?

It's not a recommended procedure from the manufacturer, but I wouldn't be surprised to hear some people say it's a great thing to make up for small variences in gasket surfaces.
Would using it cause a problem?
I've used it many times on the MP gaskets and have had no issues, I like to think it helps get a good seal and transfer heat across the gasket.

Thanks. I guess I'll use it then.
I run it if its an older engine but if both surfaces are fresh, then I don't bother. It won't hurt so if your a bit worried about seal, just use it.

I use the Mopar gasket spray intended for thier MLS headgaskets on the headgaskets I install. I've never had one leak using that stuff.
I sprayed some on two used (not for long) MP headgaskets, both held 18psi without problems. About to copper spray and reuse another one, in fact..
Dont push the red button.You hear me?

Going by the description I found online this should be it. I'm not close enough to the garage to be able to double check.

HYLOMAR! It fills all the little imperfections in the head and block. It also works great on paper gaskets because they wont stick and you can re use them
Ian Adams Function>Form 1990 shadow scrapped, too rusty:( 1991 Spirit R/T Scrapped, parts sold:( 1989 Turbo Caravan Daily beater with built-[I]ish [/I]engine slowly evolving into weekend turbo beater.
Used copper spray on a 100k mile set of headgaskets that sat in a shed for 3 years. Got them to seal after warming up the engine (and not retorquing anything). Only problem was 1 coolant passage that leaked until it warmed up.
Hylomar is good stuff but its very expensive. Use it for solid copper headgaskets. Thats how you get copper headgaskets to seal longterm. Copper is the only time I would use it but its probably better for doing stupid stuff like paper gaskets that have serious mileage on them. More expensive then the headgasket being replaced so it would not make sense to actually do it.
I am going to reuse a set of paper gaskets next month, but they were new Felpro as of last year. Swapping heads between cars.
Then the motor that had those gaskets gets a new set someday when I put it back together. I use it on new gaskets, paper and MLS. Mostly because I would rather spray then remove material from my cylinder head (weak deck). The real reason is money, the other things are justifications

Cometics are terrible headgaskets anyways. They somehow manage to make a worse MLS then OEM MLS.

All bets are off on any "used" gasket
But now I'm curious, did you coat it between the layers?
