What's the major problem you have with your piece.

It looks like the pits under the paint are as bad or worse then the exposed chrome. You yourself could grind down the pits under the paint, fill with bondo and repaint. Totally Auto has a more correct texture than what you have now. Then the painted portions would look fine; the majority of what you see.

I'm worried you are still going to have $300+ with paint detailing into your old piece that might not come out like expected.
