That specific part number is a High Temp Ceramic semi-gloss engine enamel. I found it through my research into japanning. A guy who does professional restoration of antique japanned tools tried this product, and because of the ceramic content it lays down thicker and flows just like japanning. He actually showed a comparison between a "properly" japanned tool and one sprayed with this product. There is virtually no difference.

If I can track down the original site I will share it.

I started using this on repainted parts and it not only looks correct it blends with the old japanned stuff really well.
