Header Painting How To

I've seen some post that are high on ceramic coating headers. I know its good stuff and it cuts down on heat, but a lot of people cant afford it or dont think its neccesary. I have real good luck with header paint because of the process I use to put it on. A lot of people that dont know what ceramic coat looks like think that mine are ceramic coated. Here is how I paint them.

1. Fully sand blast the header to bear white metal.
2. Dont touch the header and use wire to hang it with the collector facing down.
3. Use a lit acetalyne or propane torch and aim it into the collector so your rotating the heat to each header tube. You have to use your own judgement how hot to get them. If you get to hot it will blister the paint when applied. You also dont want to be spraying the paint while the torch is going.
4. After step 3 spray the first light coat. I like VHT paint but others work to. You need 1 can per header.
5. Right after first coat go back to step 3 and heat up the header uniformly from the inside. If its to hot it will blister.
6. Keep repeating the steps untill 1 can of paint is on the header.
7. If you dont sandblast or bead blast the headers good you might as well not do any of this. Its not gonna stick.

ANYTHING is better than that flat-black paint that most headers come with from the factory.My cousin just dropped a freshly-built 351 Cleveland in his 1973 Ford Mustang Fastback and I went up there to help him put the long-tube headers on.They were the basic-black,Hedman headers made for the swap.When we started the car,in less than 5 minutes,the paint was already cured on the headers and they didn't look very good at all.I'm going to try this process at some point in time .

Thanks for the process Full Throttle.If that process works,it's something that belongs in the HR.com Knowledge Base .

I've got a strange paint idea?

For headers, I sandblast them - or even a good sanding, and wash them down with thinners. I then apply Tremclad "barbeque" paint. With a BRUSH.
I use the tremclad paint, not a spray bomb.
It lasts unbelieveably.

When I paint an engine, block-heads, whatever, I use Tremclad from a can with a BRUSH.
The spray bombs don't stick for long, and the brushed on paint from a can gives a great shine, it even gets shinier once the engine is ran, and is easy to touch up. It lasts better than any other paint we have used on Pontiacs, in the area over the exhaust ports.

It's worth trying. Just make sure it's stirred up VERY well before using.

Here's a pic of a convertible's engine I had my kids paint with Tremclad, then while they were sleeping I touched it up- boy were THEY impressed. LOL!
The paint stuck well on the engine, and it lasted two years on the exhaust manifolds with only one touch-up...

Why everbody wants to paint their headers white, I just don't know.

They get dirty quick and don't dissipate the heat. I was told, for best head dissipation, to paint your headers dark blue. I usually paint my headers with black BBQ paint.

I did have some industrial grey heat coating that I used for a few years. I bought it at a garage sale and can't remember the name. It is still on my Pontiac's headers after 10 years, so I think it has held up pretty well.

Well Poncho62, you bring up a strange story I once witnessed with my very own eyes.
I worked at Centerline Engines for 7 years. Back then we were painting all the parts, heads, blocks, headers etc with spray bombs.
A guy had a V8 Vega that was painted Chevy orange. He was out back spary painting his exhaust manifolds blue.
We asked him why he would choose blue for the exhaust manifolds when the engine was orange, and he told us that he had done it many times, the manifolds would eventually turn white with the exhaust heat.
When he fired it up, he amazed us all. It did what he said it would. I still don't understand it to this day. It was a brand that was in a blue can with a red flag on the front, I have the name of the paint on the tip of my tongue but I can't recall it, this was back in the early 1980's.

Strange, but true!

I painted these headers a few years back when they were on my blower motor. Most street engine headers dont get hot enough to glow red unless the timing is wrong or another problem. I didn't touch them up when they went on this motor. Its just good vht high temp paint and a good sandblasted surface and heating it up.
