Don't have time? Then...
...invest some time cleaning and polishing your boat then skip the wax and Poliglow it. Five coats the first year, but they go on fast, like waxing your kitchen floor. The prep work is the key though, as whatever you don't remove you seal in and look at for the next 5-10 years LOL. After the first year you just remove any black marks or streaks with a white nylon scotchbrite pad, wash the hull and then apply 2-3 maintenance coats. Takes about 2 hours total for a 30 footer.
This spring I had yet another person come up to me and say he hadn't seen me around while he was polishing / waxing his boat, (which was a Pearson 303 some 8 years newer than mine) but was wondering what polish I used to get my boat looking so much better than his and whether I had snuck in at night in March to do it. When I told him he was looking at poliglow and I hadn't touched it since last season his jaw dropped to the pavement.
A great polish and wax job may look better, but if you don't have time (I don't) then spending about 2 hours and $30/season on Poliglow is worth its weight in gold. The only down side is that at some point it becomes time to strip it down, polish it and recoat it 5X again and although there are specialized products to do it with, it can be fun from what I understand. I haven't done it yet and from what I can tell my boat has been in poliglow for over five years and perhaps as long as ten. It just depends how anal your are about even your poliglow finish. In my case the tape stripes that are on the hull have had it and it doesn't make sense to renew them without stripping the hull of poliglow to apply them properly. I'll certainly be honest with my opinion after I go through stripping it when I do so.
I have attached a larger photo of my boat (also my Avatar photo) after two maintenance coats (not three, as I was in a hurry) two years ago. Note the reflections visible in the hull, especially the fenders in the photo in the water. I have no connection to Poliglow whatsoever...just trying to spread the good word to other hard working souls who can't find the time like me.
