Itchy, thanks for the photos. The thing is, you have the whole metallic part covered by a thick, non-transparent layer of rust. Which, I must admit, does look good. Still, I\'m trying to do something a little different: have a multiple-coloured rust (yellow, red, brown and orange tones), which would be transparent on the NMM. I tried glazing, but it takes the \"metallic\" colours of NMM away, turning the whole thing into some unidentified material, which looks a bit like copper.
@Albert: you sculpted it?!
