I remember reading that Cometic specifically recommends not to spray theirs...

I just installed my new cometics with nothing on them. I made sure the deck surface was spotless and clean and I installed everything perfectly dry and oil free. Not leaking one bit. The GM gaskets are super forgiving, don't fret.
