Is this hylomar product better than the copper spray? Are there any more experiences out there?

why do you feel you need to spray the gaskets?
they work very well in all sorts of applications w/ no additional coating...
i use it sparingly on uncoated gaskets... it has worked well in NA nitrous and supercharged engines for me in the past... but so have oem mls gaskets...
you must allow the coating to begin to cure, or "tack" in a clean place for at least 3-5 minutes, before installing them and torquing down the heads...

ill also mention, that i did once use some on an oem mls gasket in a procharged car making over 700whp w/ absolutely no sealing issues... however, whenever you want to try new coatings, you must make sure it will be compatable w/ whatever material you are going to be using it with... at the time i thought it was a good idea, but now i wouldnt think about trying something like that on an expansive motor w/o finding out first...

Hylomar is one of the best products out there, however the GM MLS gaskets are very forgiving and I have never used it on the GM gasket. I have used it on Cometics though.

I use the GM-MLS with copper spray, and i run a 300 shot and never had any problems what so ever.
