Use the stripper, it will loosen all that paint around the rivets. I used the scotch brite green pads and my hands. It came right off with the green pad. The primer is the really hard stuff to get off, if your boat is like mine. Keep in mind, I worked on my outside hull for two full weekends. This is the cheapest way to get the old paint off, but next time I will pay to have it blasted by Bayside Sandblasting. Could get the whole boat done for 150 bucks. That is worth it to me for my next project boat. Look up Sixguns mod, to get an idea of what I am talking about.
