Powdr makes a good point about turning the stock upside down. I sometimes turn the stock upside down just after I scrape the overflow off with a popsicle stick. The bedding compound is still pliable enough and will 'run' down just enough to leave a raised edge about the stock line that can later be trimmed or sanded flush. Be careful, as some bedding compounds get brittle when cured and will chip out, especially along the top edges of the barrel channel where the compound is very thin.
