We use meguiars ultimate quick wax. Spray on quick wipe off. For washing, we used to go to blue beacon but now have our own pressure washer that we can set to lower pressure than them. We use meguairs deep crystal car wash with good results but I am considering trying the meguiars boat wash. we also compound any black streaks that develop. We use la's totally awesome on the roof. Wash roof first before doing anything else. Also caulk any spots where your drip rails come together to decrease your black streak locations.
