removing aluminum anodizing

In talking to a high end professional metal polisher, those aluminum automotive trim parts are technically not the same "anodize" as let say a blue anodized Aeroquip fitting.

The automotive trim part finish/process is actually called Bright Dip.

Look at a blue anodized Aeroquip fitting. Then look at a aluminum headlight bezel. You'll see the bezel has a thicker coating and it has a gloss to it. You can sand away the blue anodizing much easier than the bright dipped headlight bezel too.

You'll find many anodizing businesses that do not do Bright Dip. Also many Bright Dip places do not have vats large enough for long 3 feet plus pieces.
