While i have no experience with anything else, I have been using the Porter Cable in conjunction with Adams pads and polishes (Swirl & Haze Remover and Fine Machine Polish) and then Meguiars Flagship Premium Marine wax. Seems to be working for me.
I do see myself trying the Collinite in the future.
I find it encouraging to know Jesus enjoyed lakes and being on boats. Matthew 13:1-2
