Welcome Glen, let me share with you one of the things I learned here that has made the biggest difference in my applications. When you are applying the tape and vinyl, the angle should be toward the raised side. In other words, the top of the squeegee should always be the back. Since I started using that method, all of my bubbles have disappeared. Somebody else please jump in here and help me with this explanation or add a link to the original thread.
