I have a 1974 Hatteras 46 convertible. I have used one of the best paint guys on the Chesapeake Bay for years. He prefers Awlgrip. He's getting up in years and he has trained his sons well. They prefer Awlgrip II. I let them paint from the rub rails up with Awlgrip II two years ago. The shine is great. I don't think the corners have held up as good as the Awlgrip however. I am considering using the Axleseal on the hull because I'm worried about the wear factor of Awlgroip II with fenders etc. etc.
