Copper coat 2mm head gasket

I have a 2mm multi-layered metal HG for my 3.1L stroker. Based on the searches I've done, I'm pretty sure I need to coat it with the copper coat spray for better sealing. Is there any tips/tricks to doing this to reduce any possible leakage? I don't think taking the gasket apart and coating each layer would be such a good idea, but should I focus around the edges of the bores and try to get some of it down in between the layers there?

 

Do I let it dry completely, or shoot it and install it tacky? F54/MN47 w/ARP studs.

When I have done the copper coat, I will spray 2 or 3 light coats waiting an hour between each. I have found that if you don't wait long enough before installing the gasket, the stuff makes a mess and doesn't work that well. I had the best success waiting 24 hours after the last coat before installation at about 60 deg outside temps. The stuff is dry enough not to "ooze" at that point and is considerably tackier. Ambient temps and humidity play a part in how fast it dries.

After the last coat, just keep testing it with your finger to see if it is still wet or tacky. Be carefull when it is tacky, as it will stick to anything and pull the coating off the gasket. Hope that is helpfull.
