So today I was cleaning my clubs. They had been sitting out in my car and since I live in Iowa so they were a little cold. When I got to my 910d and 910h I noticed that there was air escaping from the weight hole with the weight still in there when I ran the warm water to clean them. I was wondering since the air can escape from the weight hole, if water gets in there can the water make the club rust or decrease it's performance?
