I took my cast-iron intake to the machine shop to have it "baked" and blasted. They put it in a hot furnace and bake all the garbage off of it. It's generally the better way to go then hot tanking. It looked brand new when they were done with it.

I'd think hard about paint. I let them (NAPA) rush me into a primer coat with a cast iron paint over it. It said it was rated for high temperature, but once it was installed the paint and primer bubbled up around the heat risers.

If your not going to polish your intake, powder coat it. I'm going to do mine as soon as the larger oven is built. If your patient, maybe I can do it for your for alot cheaper than the "pro's". Shipping may eat up those savings though. Either way, powder coating is the way to go.
