Today I painted the exhaust manifold using a high temperature coating from Eastwood Company that is designed for exhaust components. This product is meant to have the appearance of new cast iron, which is the material the Datsun manifold is made from. My manifold had already been coated in a white material, so this should restore a more “stock” appearance.
Prior to painting I cleaned the manifold again using Simple Green to remove and dirt or grease on the surface.
The product I used is rated for up to 1200 degrees and cost about $15 for the can, which was enough to thoroughly coat this manifold.
I sprayed on one coat and then did a second coat after an hour.
Here is the final product. After the paint has dried somewhat the effect dulls to more of a cast iron appearance.
