Having done powdercoating work back in the day (I used to paint wheels, valve covers, all sorts of things) I decided to refinish them myself.
(apologies for the mix of cell phone and camera pics, I used whatever was handy)
This is what I started with. Yuck. Hard to tell, but the red had become dull with no gloss at all.
