I just put copper plus RTV on both sides of my copper header gaskets. It says it dries in an hour and fully cures in 24 hours. I don't want to risk starting the car and blowing the stuff out if it's too soft, so how long do you guys think I should wait till I start the car? Also, due to the cooler weather, the side I did first took much longer than 15 minutes to skin, so that's a factor too.
