In actuallity we used less then 1 gallon took about 3 hours with Mikes help he was management I was labor . It gets harder and harder to fit under a trailer as one gets older .The Paint was on sale $95 a gallon , paint supplies $35 It sure beats paying $ 500-1200 at a boat yard . Since Mike is moving I will be loosing my happy home (moorage at Mike's)So I want to get all the maintenance done before he leaves .
