Editing one part of a gun

**LostInTheDark** · 12-22-2012

So I was using this metallic gold tutorial, and tried to use it for an L96A1. I wanted to make my iron man sniper look better by using this fantastic gold tutorial but I couldn't figure out how to use it for just the scope or body or whatever I wanted to be gold. Instead it made the whole entire gun gold. How would I section it off and just make the scope gold? I tried to use the pen tool to cut and paste it into a new layer but again it changes all of the layers.
