I've been checking around to see what the best system is to use on an exhaust manifold. Been told powder coat won't take the heat and didn't want to do the more expensive and incorrect ceramic coating.
I was told if I do as instructed on the cast blast paint and bake it at 400 degrees, it would hold up fine. After baking, it looked really nice.
Hi Mike;
Yea... I sure did blast the it first. I did it in my booth with the big blaster and sand at 150psi inside and out. Once we made a 3 point spanner wrench we heated the end to get the nut out, I sandblasted it with the big blaster again.
It then sat a couple of weeks while I was deciding what method to use... so right before spraying and baking I tossed it into my cabinet and hit it with glass bead.
Kinda "overkill" I'd say!
The color you see is the color of the spray (baking didn't change it much).
I think it has a good look to it.... hope it's durable? Jim G.
Here you go Yates .... I just opened the pic larger in Photobucket and put Cast Blast in search to be sure.

If the wording is 1200F on Jims pic then this seems to be the one he used.
A heat resistant spray paint designed to withstand temperatures up to 1200F (648 C) on a continuous basis. Creates a porcelain-like bond at high temperatures. Resists peeling, loss of adhesion, and blistering. Must be heat cured at a minimum temperature of 400F for two hours. Do not use a primer.
Thanks Norm
Yes, my can said 1200 degrees on it and we did bake it at 400 degrees for 2 hours. Guess I got away with using it even though it says " For professional use only".
Thanks again Norm for the added information
