Best Header Paint ?
Just blew a hole out on the drivers side of my Hedman 69230 headers. Sucks cuz it's my fault I went and wrapped them. Lifetime warranty void.
I had them DIY ceramic coated with some goop from Eastwood, I airbrushed on, and prebaked in my Mom's ex Hotpoint oven. They were new in '99, I had them cleaned/sandblasted and did the Eastwood thing in '07 and that lasted thru to '18. I thought with the ceramic job, they wouldn't rust with DEI 2" mummy wrap. I was trying to lower underhood temps. Also got a hushed effect too. They got much quieter. But they blew out anyway. Eastwood no longer sells the ceramic stuff. Looking for something more durable than spray-on VHT. Also bored with black. Application is 350 SBC in '71 GMC 4x4 Jimmy, Manual Trans. Any ideas?

Re: Best Header Paint ?
For many years I have used high temp stove paint with excellent results. It is available in many colors too. I can typically buy it locally much cheaper than I see it online these days. Back in the early '80's when I started using it ,I could get a gallon for $20.
http://forrestpaint.com/stove-bright/ I would never wrap a set of headers that I wanted to last.

Do they have to be cured in the oven? I have learned my lesson.

Re: Best Header Paint ?
If your headers have lasted 15-20 years, that's not bad. And if the coating lasted more than a few years of daily use that's also not bad either.
I've found out that there is no sure-fire method to coat or paint an exhaust that will last forever. Even chromed ones will show burnt spots eventually. In the past I've tried all sorts of high temp paints but they will all eventually fade or burn off after some time.

Re: Best Header Paint ?
Ever notice old school hot rods paint their zoomies white? That is because it is Titanium based paint. Holds up better. That said, not all brands use Titanium anymore. So check those MSDS sheets.

Re: Best Header Paint ?
Here are pix of my busted hedders.
Pass side is OK, but I'm not running an L4.

That is a cool look. Jegs and Summit do not post the MDS on VHT paint though. Originally, I thought I only had a small hole caused by the rubbing of the lower clutch pushrod on the @7 downtube. I intened for my buddy to weld on a patch, and I would rewrap the headers in DEI's new Titanium banding and spray over it with their titanium spray bomb. It had a goldish look. Alas, no more wrapping headers now. Actually the clutch action did not pierce the tubing.

Re: Best Header Paint ?
No they can be cured on the engine. You just want to warm them up a little 2 or 3 times to get the paint to cure. When they stop smoking, the paint is cured.

Re: Best Header Paint ?
I used some company in Oklahoma that branched off of Jet Hot. I cut the flanges out of the box and then sent them to them. For the life of me I can.t remember the company name. After 17 years they don't shine like new but they look pretty good. This is not a daily driver.

There's a JetHot facility in Tempe, AZ, just 90 minutes north. They want about $300 more than the parts for their service.

JetHot does some fine work, but they are not cheap. For their retail rate, I would expect no less service than your friend got. Several years ago, I talked with them about coating my headers for some project. Since I'm on the NW side of Tucson, I wanted to drop off and pick them up at their Tempe, AZ outlet, ~100 miles North. They insisted on shipping. I decided it was too much money.

I then had to wire a 220 v drop to the appliance. You might shop on craigslist for a cheap one. And avoid titanium-flavored brownies. Some of my ceramic coat was flaking off after 11 years under mummy wrap. Just ordered a new pair of Headman 69230 -USA-made- hedders from Jeg's. Same p/n as the old ones, so it should bolt onto the old exhaust pipes w/o modification. Eastwood has an interesting internal header spray-on ceramic coating with a 24'' spray nozzle that shoots a 360* blast inside the tubes. P/N: 13795ZA, $27. Still not sure about the outsides. Maybe white, maybe silver. I wanted ''Titanium Blue'' like the SR-71, but I don't see it anymore. A light color would dissapate heat faster though. Some pix of the ill-fated mummification. It did look neat.

What kind of L6 and headers are you running? I have some 1978 Clifford Research long tubes on my 292 in a '68 Stepside. It's their 2nd engine. My $300 plus figure was derived from the retail price of factory coated headers as opposed to the same headers with burn-off paint.

This was on a Jeep 4.0. I forget the actual brand of header. I remember buying a raw header and having it coated was less expensive than buying a coated one.
