After some researching, I found an online retailer dedicated to airbrushing. It's tcpglobal.com. I'll be ordering my kit through them. Nice thing is they can be order through Amazon, and have the backing that comes with ordering through Amazon,
Well, it looks like the camaro will be getting an aluminum intake. It's hard to find burnt iron locally, and I don't like the way it looks. It called for burnt iron on the exhaust as well. Steel looks much more authentic. Want to do something for the exhaust manifolds. Maybe mixing flat black with a little gold metallic.
I never saw a burnt iron intake manifold (you really can't trust the color call outs on the instructions). Exhaust manifolds quickly develop a rusty iron color, maybe try mixing some powdered rust into steel or silver?
