Something new,for the guys,who wants the MR-helmets white a little darker for pics:
To make the helmet a little darker white,you can use "Tamiya weathering master" in "soot"..but VERY FINE(if you use too much,it looks like black soot!!) all over the helmet..makes it a better whitematch for pics.But I know,the different is sreenaccurate..the stunthelmets in 1976 had not exact the same colour like the Armors,too.But some guys want it a little bit better match..so that´s a possible way,to do that,without painting the complete armor.I hope that helps.
