Q. May a player put an adhesive bandage or tape on the clubhead to reduce glare or to protect the club from being damaged?

A. An adhesive bandage or tape added to the clubhead is considered an external attachment, rendering the club non-conforming (see Appendix II, Rule 1a, but see also Decision 4-1/4). However, material attached to the clubhead that does not affect the performance of the club and is semi-permanent, durable, not easily removable and conforms to the shape of the clubhead may be permitted by exception, but an adhesive bandage or tape does not fall under that exception because such items are temporary in nature and easily removable.

See "A Guide to the Rules on Clubs and Balls", Section 1a, for detailed criteria regarding permissible external attachments, such as alignment markings, protective coverings or decorative decals.

Additionally, adding such an attachment during the stipulated round would change the club's playing characteristics in breach of Rule 4-2.
