Deepsea (fantasy) diver helmet

Hi guys,
After 2 months of learning Blender from the You Tube tutorials (bless those guys!), this is my first “big” project in which I used everything I learned! There’s still some work at it, all the tubing has to be done, and the UV for the bolts are not good. I would like the bolts to be chrome and rusty, now they are just rusty, TIPS PLEASE! Also the lamps are too new, they also need an UV. I would like to hear your comments and tips! Blender rules!
