We've been using Brampton 5 minute distributed by Mitchell Golf in Centerville, OH for five years. The trick is to only mix enough for one club, and do one club at a time. Clubs can be played in half an hour. We've had a few failures, five or six out of thousands of clubs, so there's always a chance . . . Mitchell is the professional clubmakers' source for equipment and supplies. Regards, Leith Anderson
