Darker colours heat the boat up a a lot- just like a black car compared to white.. If you plan to head
further north than the seaway, into the tropics, you may regret the colour change. Darker colours used to, and still are, popular on steel
boats as they hide the rust stains. But a quick walk around any marina will tell you what sells. 'White". Ball park paint job 6-8 k.
Tip regarding the upholstery- remove the cushions
etc and get an automotive guy to do it- then replace them yourself. A marine
guy will most likely charge you a lot more. No Idea on price
other than, like anything, its impossible to even ball park without knowing the scope
of the job.
