no, it's anodize aluminum. Best approach is to wax it to prevent it from further oxidizing. Orrr... if you are feeling dangerous you can go by these recommendations below. They are listed from costly to cheapest:

1) Buy brand new ones to replace
2) Take off your existing trims, sand off the anodize coat and redo it
3) Buy restoration kit which shaves off a thin anodized layer and use water-base sealer annually to prevent oxidation
