What is the best paint to use on exhaust manifolds?

What is the most correct color match and what lasts?

Eastwood! High temp paint has worked flawlessly for me! I use a heat gun to bake it on not the oven or heat from the engine!

The manifolds were usually somewhat rusty when the cars were picked up from the dealer with overspray on the end close to the head. I used Hursh manifold dressing it turned mostly brown within a minute of running, looks a lot better in my opinion than the silver look

I have used the Eastwood paint with pretty good and long lasting results.

Last year I decided to have by buddy powdercoat a set with Eastwood's high temp powder coat. DO NOT USE IT. After a few months of use (minimal use) looks like junk. Rust all over.
And yes, he was an experienced coater. Has done other manifolds and they were ok. Maybe because my castings were quite rough with old pit holes? He did 2 coats and when he called Eastwood after it started to rust, they said he should have done like 4 coats.

Now I have to figure out if I want to take them off again (not really) or just use a dressing type stuff.

So, with any type of high temp paint the results are temporary?

I've been following this closely, as I need to do a set of cast manifolds on my coronet.
I powder coat in my shop and was thinking of using the Eastwood high temp powder - if you put 4 coats on, its gonna look as smooth as glass instead of the cast look that we all are trying to achieve.
I'll keep watching to see what everyone thinks is best.
Thanks guys!!

NO!

Ive used the eastwood stainless steel high temp coating with excellent results on three diferent sets of manifolds. Its a light grey almost silver in color. I sandblasted the manifolds and then wiped them down to remove any contaminates then brushed on the paint. I did not pre cure the manifolds but it sounds like a good idea, although a kitchen oven may not provide enough heat?

The first set I did I cant comment on now because that car was stolen the second and third sets have been done for 9 and 7 years and both still look great.

hope that helps!

I've sprayed the Eastwood manifold paint on. You thin it with Xylol from the hardware store. Works great and holds up for years. It's an excellent product.

My experience with brushing it on was that it was easy to get it too thick and the excess kind of peeled. I would never brush it on except for touch up.

Someone suggested to have the manifolds JET-HOT coated. I may try that, as I don't want to remove the manifolds to touch up in the future.

I've used the Eastwood Stainless Steel paint on several over the years. Brushed turns out a bit thicker of course than sprayed (thinned with enamel reducer) but in each case the stuff eventually greyed out a bit and seems to last forever. I have to say that the Bill Hirsch stuff is more accurate in appearance, though. It didn't take too long for the manifolds to show surface rust. Some guys used to rub in WD40 on their manifolds & headers to maintain their appearance, but it had to be done often. It usually turned into enough of a pain that eventually they'd give up.

Ive used VHT Nu Cast which is good for a heat range of 1200-2000 degrees. Looks dead on for cast iron grey also.

I tried the eastwood brush on stuff and it did not work for me. After starting the car for the first time and running it for 20 minutes it flaked and bubbled off. I pulled the manifolds off and reblasted them and now I am trying vht flame proof(1200-2000) manifold paint. If vht does not work well I will pull them off and spent the money and go with jet hot.

Like I mentioned before, if you brush the Eastwood on thick it will flake off just like you said. Try spraying it and it will work a whole lot better. You reduce it about 1 to 1 with Xylol from the hardware store paint dept. Spray a few thin coats. It sprays nice out of a touch up gun and holds up real good.

maybe ive had good luck with the Eastwood stuff because I used a foam brush or because there are TWO versions of the exhaust paint,the stainless silver and grey?
I will continue to use it and spend my savings elsewhere in the resto.

This is what I did back in about '95. It still looks great!
