OK I`ve got some strange flaking off the front of my car, the very tip of the hood. It seems like the outer layer of paint is slowly flaking off in ever-widening circles but it still looks black underneath. all the edges of the circles are sticking up a little so it`s not like I can put touch up paint on them because I don`t think it will hold. Should I sand it a little or something? I need some suggestions. Thanks in advance.
