Hey, Thanks! The steel is just a sprayed base coat of dark brown with AK Interactive Dark Steel Powder (powdered graphite) brushed on and then lightly buffed with a brush/rag/finger. Very easy, (if somewhat messy) technique!
I checked your website out and I must say, your Alpha Legion are brilliant.
Truly one of the nicest Marine armies I've seen. And these Jetbikers are my favourites.
Really impressed with the weathering and the overall theme of the models. Especially the subtle iconography (Very Alpha Legion)
I would love to know how you painted the iron parts on these bikes!
I also hope you post the rest of your army :)
