Black Gills?

[Chillioil]

Some people here mixed up the front Grill and Side Gill. OP you can try IND or ebay, IMO they are pretty much made by the same manufacture from Taiwan. BTW it is PITA to remove the side gill.

Take to your local bodyshop and have them paint matt or gloss finish to your linking. That's what IND does. You can send them to IND for repainting, but local will be cheaper.
They can also tint the markers.
