Jeweller's rouge achieves stunningly smooth results when used to polish metals. The rouge comes in several colours, each of which represents a different grit. Powders of varying fineness make up the rouge compounds. The best colour for a specific project depends on the metal, its condition and the smoothness of the sheen desired. According to jeweller's rouge manufacturer Schaffner Manufacturing Co., white "produces a clear, brilliant, mirror-like finish" on aluminium. However, you must first polish scratched aluminium with a grittier jeweller's rouge and then repolish it with progressively finer-grit rouges until you've removed the scratches; then apply a finish polish.

Attach a buffing wheel attachment to a power drill.
Apply a small amount of rouge to the wheel by touching it to the rouge as it spins.
Touch the spinning buffing wheel to the part of the aluminium you plan to polish. Move the wheel back and forth over the surface using light, even pressure.
Apply additional rouge to the buffing wheel as needed.
