How to model gold plating traces on non-planar contiguous surfaces?

Hi,

I want to add gold plated circuit traces along the surface of the attached plastic part.(The plating will start from the front nose just after the fillet and extend along the surface of the front shaft, then up the wall and along the surface of the larger diamter back shaft.The traces will be a series of narrow traces around the circumference.

What is the best way to do this? The wrap feature does not work for this requirement.

Thank you,

Matt
