Thanks Blue!
Yes they edges are lot smoother now and they did a good job of using the rubber molding on the edges to insure a snug and cut free edges. I am going to during the winter months devise a new lid for the Wizair to work in conjuction with my ram air hood. I really do not wish to tear up the original unit, so I am going to have to try and fashion a new one to tear into that one.
Should be an interesting project.
