In Gimp:
1. Select them. Since it's square, I used rectangle select tool, then trimmed off the excess with the free select. If you hold down Shift or Ctrl, you can add or subtract from the selection are, respectively.
2. Play with the the tools under the Colors menu. For these handles (chrome to black), I think I did "Colorify" to a darkish shade of gray, then played with the Brightness/Contrast tool a little. Depending on the picture taken, you might have to play with the color balance as well. In this case, the blacks have a hint of magenta to them, so I added a little (might have been too much) bit of magenta and yellow.
If you're doing, say, chrome to another color, the colorize tool might be useful.
3. Once I got it close, I added some blur (Filters -> Blur -> Gaussian blur -> 1 pixel horizontal/vertical) as well as some noise (Filters -> Noise -> RGB Noise -> .03 red, .02 blue, .02 green). These will just depend how "noisy" and blurry the picture is.
That is more or less my way of doing PTMing in Gimp. I'm sure there are better ways, and eventually, I wish to find them. But mostly, just play around with it. You'll get the hang of it.

If you were talking about PTMing in real life, I think the process involves some sanding of the chrome, adhesion promoter/primer, a couple coats of base coat, a couple coats of clear, and some wet sanding.
