Plating over solid body.

I have a solid part that I need to add a .002" plating on all surfaces.  I need these to be two seperate solid bodies in the part file. I have tried the "Indent" and the "Combine" commands after "Shelling" the body but still cannot get to a point where I have a solid body with a .002" thick solid body plating/coating on it. Any Ideas on how to do this?

See attached file.

Thanks
