    Don't chrome it sand it down and POLISH IT!! Get the 3 polishing cakes and go through the stages and it will shine like just as good as chrome.

    If you polish or sand the aluminium make sure you wear a respirator or quality mask as breathing the airborne matter is believed to contribute to Alzheimers.

    Only wet sand aluminum and do it by hand. Aluminum powder is not only harmful but super dangerous. It can actually explode. You don't want to be anywhere around when that happens.

    What are the fire and explosion dangers associated with aluminum powder (uncoated)?
    Reactive flammable solid. Bulk aluminum powder or dust in contact with water may heat spontaneously. Moist, finely divided aluminum powder may ignite in air, with the formation of flammable hydrogen gas. The hazard increases as the aluminum particle size decreases. Contact of burning aluminum with water forms flammable hydrogen gas, an extremely dangerous explosion hazard, particularly if the fire is in a confined area. Bulk aluminum metal itself is not combustible.

    Under certain conditions, a dust cloud of aluminum powder can explode when ignited by a spark or flame. When evaluating the explosion hazard of a specific process or sample of material, the important factors to consider include: particle size and shape, dust concentration, the nature of any impurities, oxygen concentration, humidity, and extent of containment. Explosions of aluminum dusts have occurred in industry.

    IGNITION SENSITIVITY: 1.4 (aluminum, atomized); 7.3 (aluminum, flake)

    EXPLOSION SEVERITY: 7.7 (aluminum, atomized); 10.2 (aluminum, flake)

    The EXPLOSIBILITY INDEX is greater than 10 for both atomized and flake aluminum. This value indicates that a "severe" explosion could occur. This hazard rating index is calculated by multiplying the ignition sensitivity (ignition temperature, concentration, etc.) and the explosion severity (explosion pressure, rate of pressure rise).

    MINIMUM IGNITION TEMPERATURE: 650 deg C (1202 deg F) (cloud); 760 deg C (1400 deg F) (layer) (aluminum, atomized); 610 deg C (1130 deg F) (cloud); 320-326 deg C (608-619 deg F) (layer) (aluminum, flake); 420 deg C (788 deg F) (aluminum, 6 µm)

    MINIMUM CLOUD IGNITION ENERGY: 50 millijoules (mJ) (aluminum, atomized); 10 mJ (aluminum, flake); 13 mJ (aluminum, 6 µm); 28 mJ (aluminum, 17 µm)

    MAXIMUM EXPLOSION PRESSURE: 579.2 kPa (84 psi) (aluminum, atomized); 875.7 kPa (127 psi or 8.8 bar) (aluminum, flake); 640 kPa (6.4 bar) (aluminum, 6 µm); 700 kPa (7.0 bar) (aluminum, 17 µm); 540 kPa (5.4 bar) (aluminum, 100 µm)

    MAXIMUM RATE OF PRESSURE RISE: Greater than 138000 kPa/sec (greater than 20000 psi/sec or 1380 bar/sec) (aluminum, atomized and flake); 133100 kPa/sec (1331 bar/sec) (aluminum, 6 µm); 62100 kPa/sec (621 bar/sec) (aluminum, 17 µm); 13500 kPa/sec (135 bar/sec) (aluminum, 100 µm)
