Hello everyone...I’ve been searching multiple hours trying to find the correct way to repaint my interior aluminum boat ...the paint is not chipping...it’s very dirty and old looking.....I’ve read where I need to strip paint...just sand paint and I even called the paint company that I’m going to use and he told me not to even use soap to clean before I repaint....he said to just use a brush and water to scrub and prime after it’s dried and then repaint....I’m getting conflicting advice and I don’t know what to do. Any help would be greatly appreciated
