Default Header Coating

What is the best coating for headers?

Iíve done powdercoating in the past but decided to try Polydyn on my 65. Iím not impressed, they have only been on the car maybe 8 months and I havenít even driven the car much but the coating is already coming off. They told me it cools just a few minutes after shutting the car off, but the headers are still hot after 20 mins of running the car.

What do you guys recommend?

Thanks!

I have McJacks headers that are metal/ceramic coated on the outside and copper coated on the inside. They still look great after 7+ years.

It is a metallic ceramic coating that was used exclusively in the aircraft industry, google jet hot coatings.

Ceramic coating seems the best from what I have used. I tried aluminum spray coating on a set of cast iron manifolds and still found rust within a year.

Now VHT has some rattle can coating they advertise for coating pistons that I would like to try because it's like only 10 bucks a can verses $200+ for ceramic coating.

If your not in a hurry it can be fun to shop around looking at all the new coatings are out there now as technology keeps growing. I know Jet Hot advertises ceramic coating in many different colors.

Most companies offer a coated version. If you are thinking of taking your headers and sending them out for coating, it probably isn’t worth it. By the time you pay shipping 2x, prep, and coating, you can have a brand new set of coated Hedmans delivered for about $500. Sell your old ones.

What about stainless?
Do they just turn colors?

It is my recollection that Crest Coatings in Anaheim, CA did the ceramic coating on my headers, gotta be well over 25 years ago and they still look like when I brought them home from there. They were also doing formula one cars at the time.

Jet hot is a good coating but don't buy their hype about engine bay being 10 or 15 degrees cooler cause it's a bunch of crap.

The VHT ceramic paint is what I use to coat the Header Power Brackets. There are several on this forum who have purchased Header Power Brackets. Mine looks the same as when I started the business 8 years ago. But the bracket does not conduct hot exhaust gases like the headers do. Maybe others could report on theirs.

Default Jet Hot Ceramic Coating

I've got an old but solid set of S&S Headers on my smallblock '56 Nomad and contacted Jet Hot to get an estimate for ceramic coating. The price was $300 but as already mentioned, the shipping both ways adds up enough to warrant looking at new headers. By the way, if you sent them a set of headers that still had remnants of an old ceramic coating still on them, there's an additional charge of around $50 to remove it. Back about a dozen years ago when I worked in South San Francisco, I took two pairs of new/painted headers over to Sanderson Headers, just a few miles away from work, and for around $180 a pair, they ceramic coated them and came out looking great and no shipping involved.

Had my stock L72 CI manifolds ceramic coated. I think is was about $150 for the pair. Look like new but it’s only been abt 2 yrs.

I have had very good luck with the VHT Flameproof. Seems to be very durable . It's cheap easy and tough. I had an oil leak that stained my headers after the VHT cured and was able to wipe them down with lacquer thinner ! No harm.
