I'm working on a costume that has armour, seen here
I've decided to make it out of latex, reinforcing the front and back sections whilst leaving the area just below the arms softer for comfort's sake.
My question is about giving it a metallic finish so that it's closer to resembling armour.
I'm planning on tinting the latex first, to give it a base colour.
Will Rub'n'Buff work on latex? Or is there a better option to create the finish?
Am I going in the completely wrong direction?
