Yep I tried it, because of the close space between the neck and trap section it is almost impossible to get the undercoat to lay down glossy, ends up very dry spray so the chrome looks awful. :unsure This really looks pretty darn good for silver paint, pretty happy with it.
What? Not sure I understand, this is a one off. Hand drilled rivets and my newest 4 piece Mark2 helmet with hinged jaw and faceplate, haven't made any others and don't expect to.
