I used this on a manifold from my 455 in my GS. The paint is very thin but goes on nicely. Just use thin coats so it does not run. I prep'd by sandblasting the manifold and wiping down with lacquer thinner. The can is really small but the paint goes a long way. I used maybe 1/10th of the can to do two coats on one manifold. The paint cures with heat so it's a little soft and easy to damage until its heated. My other choice was Calyx but I went with the POR as I wanted a paint. It's also very dark - not sure I like it or not. It does come in an "aluminum" color. See the pics: I will follow up after its back in the car and "cured".
