Darren - no just regular aluminum paint... I am doing the cockpit floor and such in that as the aluminum from alclad is a little shiny for that... Just wanted to give some texture contrast as well...
The cylinders are MM buffable Burnt Metal with no wash, the center hub showing through the metal shield is MM Aluminum, the shield itself is AlcladII Aluminum, as is the prop.
I shot the Burnt metal on the cylinders while still on the sprue, detached and placed them on the block which was done in aluminum. I then used a pipe cleaner to shine the smooth pieces of the cylinders a bit to provide some contrast. MM acylic red is what I used on the wires. Testors spray gloss black did the pushrods justice, with MM Aluminum covering the crankcase center (re: the hub inthe shield is the sleeve for the prop shaft) Testors gloss black also covered the shield and prop, then I shot Alclad II over it. I may go back over a few pieces with either duraluminium or dark aluminum to give more contrast on the shiny metal parts... I need to trim the ends of the pushrods still to allow them to sit under the cylinder heads properly and touch up some of the gloss black on the lower pushrods where I overshot with aluminum from the crankcase area...
And yeah... as for the Iwata ... it's that nice!!!
