Can you assist me in getting advice on refinishing a previously painted 14 ft, vee-bottom aluminum boat (bottom and upper hull). What prep, primer and finish coat should be used? It will be used as a duck blind (camo) and fishing boat (fresh water). We have it sanded down to exposed metal with minor feathering of remaining body putty and primer now. Should it all be uniformally exposed metal and then what? Send me any additional information that can help me with this project, especially prep and primer.<br /> <br />Please help.<br />Noluck127
