As explained to me by the expert who restored and re-anodized my aluminum tail panel, the Metro wheel opening moldings were made of the wrong material and are dull anodized, not bright anodized.

They are made from extruded aluminum, not sheet aluminum as the originals are. Extruded aluminum is a different chemistry than sheet aluminum and does not anodize well. In addition, the extruded aluminum is very stiff and springy, while the original sheet ones are soft.

I re-sold my Metro pieces to somebody else due to the non-bright appearance and bought a set of Layson's which is made of the correct sheet and bright anodized. The photo shows an unpolished original at top, a dull Metro in the middle, and a bright Layson's at bottom.

As to the molding holes, some restoration shops weld up the original body holes and re-drill according to the holes in the molding for a precise fit.
