The LINE-X itself dries crazy fast. I mean, minutes. The Premium UV top coat dries to the touch fast but you need to let it cure for about a day. As in, we couldn't reinstall the rails or close the tailgate until today. If we had just done the LINE-X, I'm pretty sure we would have been good to go right then and there.Did you have to keep it covered or anything? As in how quick did it dry?
