Exhaust Manifold Treatment

[bob32268]

What is a good product to use for treatment of exhaust manifolds to make them look like "new" cast iron?
I've been using VHT Cast iron paint, it looks nice but has a tendency to "burn-off" or discolor after about an hour or
so of driving. Does anyone make a better, long lasting product for this issue?
Tks,

Did you blast them clean and then bake and cure the paint before install. I have over 3500 miles on mine now and still look fine...

I like Eastwood brush on

I used VHT cast iron high heat paint and baked and cured it on my Barbeque per instructions on can. My wife doesn't let me use her oven any more. LOL

What these guys ^^^ said. Shake and bake. Shake the can, bake the manifolds.

A lot of guys on here don't like POR 15 products, but I bead blast my manifolds and use their cast blast brush on coating. Once the engine is cranked the manifolds will smoke and cure with the engine heat. The manifolds on my Superbird have been done for 23 years and still look as good as the day I first started the engine.

What he said above ^. Been using this for ten plus years and never had a complaint.

Here's the VHT product that I have been using:

 

[Jeff Peterson]

The manifolds are hotter than 550* at idle

 

[copper67sat]

Eastwood brush-on after 30 yrs and about 30k miles. Cured on the engine during break-in.

You need to use the SP998 VHT 1300deg paint for manifolds.

 

[AR67GTX]

Correct, the VHT paint you used is block paint. It won’t take exhaust temperatures.
