What’s the best Hi-temp manifold paint?

[69polara440]

Getting ready to paint my HP manifolds with cast look paint. Which paint lasts the longest?

 

[Newport 66]

I jet hot coated mine. Been 5 years and around 10,000 miles and they still look good.
Not a current picture, but I can get one in the morning.

This is what I used on the cast headers on my 300J six years and 16K ago. They still look as good now as the day I painted them.

I may look at that! Got an exhaust leak on the passenger side..... off with the manifold. Really thinking about having a shop put up bigger head pipes.

I've used the eastwoods manifold paint for many years, holds up well.

I have had great results with this.

I second Eastwoods.
For best results glass bead the manifolds, then use a light Scotchbrite pad then clean clean CLEAN!
I did mine in 2009 but again driving the car last 3 years and well over 10000 miles. A wee bit of burn off at #1 ..Still look great....

I'm going to try this old method on my HP manifolds. Graphite spray. You touch it up with a rag once a year sprayed with the graphite. We will see.

If you do that, make sure you are wearing clothes that you don't care about. When the graphite overspray/splatter hits, it's on there for good. DAMHIK

Interesting ,I have done 2 manifolds already and haven't had that problem. I use dry graphite film lube and doesn't make a mess at all. No splatter.

That’s pretty neat. Kim

 

[Turboomni]

We shall see how well it works. I first saw this on a Ford model t channel and the one I posted above. I thought it was worth a try.

Here is a pic after touching it both hp manifolds. See there isn't any splatter. I will give a report after they are on the engine awhile.

So the Jet-Hot coating quote came in at $413! Too rich for my blood!

 

[Turboomni]

Jet Hot Coating is amazing stuff I had done on another car. Yes it is expensive and good.

i used por15 on my bbc...had my powder coater blast the manifolds , i sprayed them then he cured them at 300 as per their instructions...10 years later i just see rust creeping back through them....and the truck has only been driven about 10 miles since then and is garaged...so the hp manifolds went to jet hot this time

I used POR 15 manifold grey worked really good for me touch up every few years with a sponge brush
