Got my beautiful Cold Cast Boba helmet from Asok today and I want to get started on it. Is steel wool all I need to polish it to a metal finish? Is there some kind of metal polish to be used as well? Are there steps to be taken like finishing a paint job on a model car, i.e. progressively finer sandpaper and then a polishing compound. Any advice will be appreciated. It is so smooth and nice looking right now, I don't want to screw it up!
