Hey Getting a shiney metal surface depends on a lot of things post a picture of the scene you are working on and I may be a little more help to you! If its just a single object it will need something to reflect! If i have time i will try to make up a reflective material for you to see as an example! You should also look on line for Maya shaders if they are not just right atleast they may be able to send you in the right direction!
