The Self agglomerating tape from Scotch is really great. You just pull the white protective tape from the sweatband and then wraps it, pulling it in tension to the point that is to be sealed. It does not matter if the place is wet or dry, rough or smooth or greasy or whatever. If you have wrapped the leak Pressing the elongated end of a call, and it connects to the rest of the band. This then completed seal is not only an interim solution but holds truly permanent. Simply brilliant.
