For 7 yrs off and on i lived in a 38 ft sea ray boat in the keys that i owned. It was painted 9 times with a mohair roller to change its apperance. The problem with the paint job is (1) it will only work with a very limited brand of paints. (2) The color selections are very limited, but when done propperly the results are outstanding.The paint i used was Interlux brightside polyurethane single stage. We took a 9 in prof mohair roller cover and cut it in half to make 4 in rollers, then we washed it in a washing machine and dryed it to remove all the loose hair, and you are ready to go.I dont know how long the paintjob lasts.
