Painting TOPY wheels

*So I’ve been trying to find a “correct” black paint to match my TOPY wheel. Despite googling several searches with no luck, I tried a few types of paint flat, matte, etc. none looked right when comparing to my original spare. By chance I had a can of black high temp stove paint. Gave it a try and was surprised to see it was a very close match to my spare. The paint used is Black Rustolem High Heat.
 

For inside the wheel, I used Seymour Alumiblast, which is a bit to bright compared to the spare. 
Does anyone know of a closer matching paint?
