Give it at LEAST 30 minutes to cure, or you'll get the stuff ALL OVER your barrel. And that's bad.
Actually, if you can grin and bear it, just try that. Walk around with the gun uncocked, and remember to pump it before you shoot. It will prevent the likelyhood of a rollout that way.
May save you a lot of headache. I'll keep loking for a tightbore Phantom barrel meself.
