Painting exaust manifolds?

Rick-14032 · May 29, 2019

Hi Guys, I'm in the finishing steps of a restoration on a 1945 Farmall Model A. I have most of the painting done. I haven't painted the exhaust manifold. It really kind of sticks out like a sore thumb. I've used heat paint on other projects. But I don't know what kind of temperatures an exhaust manifold gets to. Would it work if I take the manifold off and paint it black with heat paint? Or would the manifold be too hot for the paint?

Eastwoods has a gray that I think looks very good. It is supposed to look like an original exhaust manifold and is good to 1400 degrees.

The VHT FLAMEPROOF COATING is another good product.

Black barbecue paint will hold up longer than you think it would, but eventually just goes away.

I've never had any luck with rattle can high temp paint. The last time I used VHT Flameproof and it's holding up well.

It is common to see a manifold glow red in the evening when you are working a tractor engine. I am looking a chart of Steel Color vs. Temperature, Ref. ASA Aviation Mechanics Handbook. A faint red starts at 900 F with Cherry Red at 1375 F. You will want to use a high temperature paint for exhaust systems.

I think if your manifold is glowing your timing is off a little.

Most of the stuff you'll see in the hardware store is silicone polyester, good for around 500?. This is mainly for stove pipe, we produce a few million pounds of coil a
month for this purpose. You need a silicone polymerized coating which like the previous poster suggested which is good for around 1500?.

I like Eastwoods Cast Iron Grey . Good product high temp rating.

I've used Eastwoods paint too and it does work good. This time I epoxied the intake/exhaust manifold and painted it the tractor color using a urethane enamel. It has survived an hour of run time so far without any color change.
