I haven't done it with a Duo, but I have used this process on other
plastics:
Step 1 Metal Polish
Step 2 Plastic Polish
Step 3 UV Resistant Protector.
The metal polish will remove a thin top layer of plastic. The plastic polish
will then smooth out the top layer. Finally, the protectant with UV
inhibitors will help prevent any future yellowing. I've also heard of using
nail polish remover with acetone, or a car buffer in the place of the metal
polish.
Just be sure to be careful of any decals or labels - anything that takes off
a thin top layer of plastic will take off decals and labels as well.
