I see I see. Thank you. I think for now i'll stick with acrylic air paints like Vallejo until i get more confident.
I'm looking for a way to make a polished iron look.
the original idea is to have a black glossy primer, sprayed over top is a thin coat of very dark metallic steel/iron color
wash it down with some nuln oil/drakenhof nightshade
then a final layer of a lighter metallic mixed with a little blue to give it some tint.
Highlight with bright silver, add rust and weathering, finish the trim with a color i havnt decided yet
Something similar to this user's marines.
