    cleaning engines

    is it possible to get a near mirror finish on your engine without chroming, just by sanding down starting with 200 grit and moving upwards to 2000?

    Yes but you finish with buffing wheel and compound. Make sure you work outside and wear a respirator as the dust is not good for you.

    200 grit bit coarse to start with I reckon. 320 or 400 grit better, otherwise you're sanding out scratches fron the abrasives if not careful.

    If you're thinking of polishing the whole engine, you'll have your work cut out.
    To polish the casings I'd start with 80 grit wet and dry, if they're in poor condition. Followed by 120, 180, 240, 320, and 400.
    Then polish with coarse, medium, fine mops, and compound.

    There is not enough money in the world to get me to polish an entire engine to a near mirror finish. Once you start, you're commited. Then when it's done you need to maintain it? HELL no.
