Applying colour to a shaded area

[SpookTheHamster]

What method would you use in Photoshop to apply colour to the white areas of the render attached, while retaining the shading and shininess of the render? (ignore the horrible blotchy area)

I'm specifically trying to make it appear to be painted black. I've tried using the brush on a second layer and then reducing the opacity, but that gives me a dull grey. The closest I got was using the brush tool on the same layer with the Overlay setting, but that sometimes returns weird colours, or makes no difference at all.

Doing this sort of thing in Photoshop is not what I normally do, I generally only use it for touching up actual photos, so I've never had to play around with recolouring before.

Here's how I'd do it ...

1. Make a masked layer of the area you want colored.

2. Use the original image to overlay on top to keep the shading.

2b. I used the image to mask itself in order to create a little more dramatic highlight/shade effect.
