Go to a camping type store e.g Rays and get a pack of the evo foam squares, theres usually 4 in a pack. Its soft, gentle of the hull and anything that shouldn't be on there like sand or little rocks you can easily brush off with hand. I used it on my wheels, my trailer and even have a couple of 100mm strips on top of sawhorses when i'm working on the boat, cost about $20 - $25 for the pack and squares are about 600mm x 600mm x 13mm thick, cut it with a stanley knife or scissors
