Ever Polish Cast Iron??

[cycledog]

I may have posted this on KB a long time ago. Can't remember. Any way, ever polish cast iron? It can be done, with lots of work. Here is the manifold on my 64 GMC. I polished it and then powder coated it with clear powder, don't know if I had the oven too hot or it was impurities in the metal. It came out a gold color, didn't like it at first but it grew on me. I also powdered the valve covers, pulleys and mc cover.

I've never done it but yours looks good. I like the gold tint on the manifold. Did you do your own powder coating c-dog?

Yes, I did the powder coating. I've got an old kitchen oven in the shop and a toaster oven for the small stuff like hardware etc.

With a lot of work It all started by just trying to remove the casting marks and fireing order smoothed off and just went crazy from there. I used a dremel tool, mini die grinder and a small pneumatic belt sander and many hours.

Glad you got pix because i never would have believed it. Only a small percentage of those who see it will know what they are looking at but those who do will be amazed

cast is cast, even aluminum comes out pretty ruff. That' why a polished intake cost more...elbow greese is an expensive lubricant.
Great job!
