    You basically have to grind and sand it away if it's the really chalky stuff.
    First you dissolve the "clear coat" which is yellow with auto paint remover (Aircraft Remover here)
    Fins might need a fine stainless wire brush or a welder's wire brush, really depends on how nasty things are. Then 3M or ScotchBrite scrubbies and "washing-up" liquid.

    Search "Mad_Bohemian" on this site for polishing tips. It's a multi-step process.

    I think Den is talking more about the engine itself, rather than the covers. About the only way I know of to get the engine clean is some sort of blasting process. It still would require a lot of clean up afterward, and there would be areas you can't get to. It's almost easier to remove the motor, plus it would very hard to paint the motor still in the frame. I wish there was an easy way to clean the motor in the frame since VooDoo is getting a lot of chips on the motor paint. You could probably do it by hand, but it will be a slow, laborious jobs...maybe someone has a way... I haven't found it :)

    Here's the thing...once the engine is clean you'll notice how dirty the frame is, so the engine will have to come out. Then you'll notice the wheels aren't so hot looking either. Then....

    It's a vicious process. Best not to start.

    No truer statement! The worst becomes the best, which points to the worst, which then becomes the best, which points to the worst, and so on.

    Trust me, it's like a drug, you never get enough. And once you completely do the bike. You start looking elsewhere for a (restore) fix.
