I went to a book on rules incidents that I have at work and it didn't mention this, although I seem to recall reading about it somewhere.
The Faldo / Lyle incident is mentioned. It took place in the Kenyan Open many years ago. Lyle was DQ'ed for putting the tape on in the middle of the round.
Adrian, it is against the rules to put something on the face of your club to modify the playing characteristics. Some players believe that wetting the face will cause the ball to fly lower and run more.
