You should buy shader ops but..... Make a copy of the scene (or use the original)& have just the eagle in it. Use the remove unused shaders option to clear out any duplicate shaders. Delete all the shaders in the copy scene until just the defalt shader is left. Adjust this to your metallic taste or drop one of the presets on it in the shader room. Everything will be shaded the same. If you need to bring your chrome eagle back into the first scene (with other objects and shaders) rename that one shader to something other than default and save the eagle to the browser so you can drop it into the scene. mdc DCG plug-in is much faster and does much more than this
