I have had no trouble with the good old Halfords rattle cans (apart from the price - a big boat seems to eat up paint!). The grey primer followed by several coats of your chosen colour has been pretty reliable for me. And you get a very large choice of colours. My only issues have been when I didn't prepare properly. So rub down, wipe clean, wipe clean again, keep your greasy fingers off the surface, shake the can thoroughly, then give it another minute, and only spray when the temperature is mild and there's little wind. I am sorry to say that November isn't the ideal time to spray!
