Sure thing. For this one i colored the letters with a gradient making the center dark, then made a path for a mask. After that the white highlight is a white to clear gradient centered on the text and the "dips" in it are just the brush tool set to zero hardness and brushed in. That helps with the metal. Its just alot of fuzzing the highlights, a little graininess helps too. Hope that helps!
by the way what font is it?
