Bill, I used Dupli Color high heat ceramic 1200 degree paint from a local parts store and it's holding up real well. I cured it according to instructions, in my oven, in 3 stages. But that went on over a previous coat that was already on my manifold, that looked like a silver brushed on paint. I wish I knew what the silver was, it appears to be indestructible.

I still like the POR 15 hi temp stuff in the pint can, applied with a small

brush. Has held up better for me than previous rattle can paint.

Using the brush gives me a little heavier coat than spray.

Hi, I have to agree with Norm, you need to get some miles duration of the engine running at full temp, then if it holds up, great.

I used the Tremclad High heat enamel good to 700 degrees, wire wheel and solvent prep, if it holds up great, if not who cares, not gonna ruin my ride, and fun with the car...........Fred

I think the original coating on my exhaust must have been something like POR-20. When I prepped it for the black dupli color, The silver brushed on stuff was the toughest stuff I've run across.

Norm,

I agree that the trust test will be actual driving. However I have the same paint on my wood burning stove and after five years it has held up, even to boiled over kettles. I had problems with my fuel lines which leaked gas on a hot manifold and it cleaned up no problem. This stuff is made for these kinds of applications. This is what reads on the can...

Stove Bright is made for wood, pellet and gas stoves, pipes and boilers, furnaces, radiators, engines, auto headers, manifolds, heaters, mufflers and cast aluminum barbecues with in-service temps to 1200f. Maintains excellent color to 900f and good color to 1200f.
