• Wonder when every one says make sure no bubbles under the tape

    When I apply the tape. If you start with no bubbles, your job on that front is done. To ensure a good bond before exposing the tape to service conditions, I press down on it with a sheet of rubber and a pressure of about 500kPa. It's easiest to do this if you form the rubber sheet into a torus and constrain the part not pushing on the tape with a fabric bag.
