After TONS of cleaning, I finally decided on which paint to use. I went with a 1200 degree ceramic based engine paint i had sitting in my garage. I had nearly a full can left from an old project. It seemed to go on the smoothest when i rubbed it on.
Yes, i said rubbed it on… meaning i didn’t spray or brush the paint on, i actually rubbed it into the metal with a rag. After i finished, if needed, i would go over an area with a very light spray.
I desperately wanted the POR 15 engine enamel to work but it did not brush on very smoothly. It went on VERY thick and adds an entirely new surface to whatever you are painting (i tested on a BMW valve cover for my 2002). It looked almost like a powder coat type surface.
It sprayed OK but i didn’t want to spray my parts and worry about masking everything off. The rub technique worked well at times, and not at others.
If you buy it, i do recommend thinning and spraying it. It is actually a nice product. I sprayed one side of a 318i manifold and it looks pretty good. i think the thinner and the spray helped it not go on so cake-like.
Anyhow, back to my ceramic based high temp paint… I started with the final drive and front brake hub. When i finished those, i went to look for more paint only to find out it was discontinued about 2 years ago.
Douph! Just my luck…
I began to think of how much paint i wasted on testing, and spraying other stuff…
With fingers crossed, i made it through the project with enough paint to spare for touch ups (if needed). Phew… it was a nail biter though.
