I need to do some good cleaning. Been riding in the rain way too much lately (fl in the summer, at any given time its 30 minutes from a rain shower). The flat aluminum parts of the motor are not as bright as when I got it. Obvious start is soap and water, but what can I use to brighten it up? I have seen threads talking about using paint and a scotch pad. I can think of stuff like barkeepers friend and other "abrasives", but am concerned about making it too bright or scratching. I dont want to polish it bright either! I have used choke and carb cleaner on my aluminum high rise car manifolds in the past. Next, is there anything I can use to protect it from dulling and staining so fast (other than not riding in the rain)? Thanks guys and girls!!!!
