My cost for painting a boat is around £50 a foot. For that the roof receives 5 coats of paint and any sanded areas recieves an additional 2 coats. The sides get 3 coats and more if necessary . The price also includes any signwriting and artwork, which I love to do. It does not include the hire of a facility. I know my prices are much cheaper than other painters, but to me my prices are fair, and I’m used to having happy customers..
