Here's the progress pics of Hammerstine. He was primered in a few shades of grey first then naturel sea salt was very liberally stuck to his armore plates and then he was oversprayed with red. By the time id done this a lot of salt had come away so i reaplied more salt and used (i think) fire wastes orange (old citadel paint)
After this the salt was scrubbed off with a tooth brush and for reasons unknown to me i then applied sunburst yelow ink. Next up will be the the oil washes and the cabeling on his chest and arms and legs.
Before i forget i should mention i used a very old can of elnett hairspray to stick the salt on.
There are some very good how too's online about the salt weathering tech.
