I had an extensive conversation with the local powder coater and he said they use either degree temp or degree temp, and every time you get things hotter than that it will get sticky again. Once it's sticky every bit of dirt and crud will stick to the "wet" coating and soon it will look ugly. If it gets way over the curing temp it will simply bubble and smoke away.

Ceramic coat is the way to go. Another great option is porcelain. Joined: Apr 1, Posts: Profile Page. Joined: Dec 9, Posts: Profile Page. It will work perfectly Lucky3 , May 13, Joined: Oct 10, Posts: 1, Profile Page. I used Eastwoods white "ceramic" coating on my headers and cured it by running on an engine stand for 45 min. So far so good; the car isn't on the road yet. Joined: Jun 13, Posts: 1, Profile Page. I used a coater from White City, OR just outside of Medford about 20 years ago to put on some high temp powder?
Not a great photo, but the coating has stayed on and not flaked or significantly discolored. Russ B , May 13, Joined: Mar 12, Posts: 1, Profile Page. I used vht header paint It sucked.

Joined: Dec 31, Posts: 62 Profile Page. I bought some small block Chev ramshorn manifolds of ebay as I thought they where ceramic coated at least thats what the add said.
They looked great till I started the car and within 10 minutes most of the coating had melted off. Guess what they where powder coated but they sure did look good before the engine had been run.
Anyway I think this answers your question no you cant powdercoat headers as it will melt of within about 20 minutes of the engine being started. There wasnt a fire but I reckon it might have come close as there was lots of smoke and man they sure did look crap after the coating had melted off. I put the old ones back on.

He blasted the coating off of them not an easy job , cleaned them, re baked to get them up to temp, and re coated them again.
And they bubbled up again in the same place. He said he was afraid to blast them again for fear he'd blow a hole in them. He did NOT charge me, and the area where they bubbled is below the floor and not visible, but even where it bubbled, its still on there, it didn't flake off. My powdercoater says that there is something in the metal that gasses out when baked and wont let the powder stick. He's done a lot of headers, and he said that this is the first set he couldn't get correct.
Im not a powdercoater, but this guy knows his stuff, didn't charge me, and told me if it flaked off to bring them back and he'd do them again for free. None of it came off. The powdercoating I had done was equivalent to the ceramic coating I had on the Dynomax headers I took off.
I've got no complaints. The Summit headers fit great, but they didn't take coating well around the collectors. If you can live with that, I would recommend having the Summit headers and having them coated. You wont be sorry. Nov 23, 5. Thanx guys now i just need to find a set , im leaning towards shorties, Andy Jensen just called and said my engine is finished and ready to be picked up. But i wont be able to get it till least next week due to work , then i need to start gathering all the other goodies , the headers new alt brackets etc Nov 23, 6.
Also, the high-temp powder It withstands high heat, to the point of glowing, and cools to the touch quickly. Nov 23, 7. Messages: 3, Likes Received: 4. If you have researched deeply on powder-coated exhaust headers, you may have come across another option that entails powder-coated exhaust headers that have been formulated to withstand high temperatures.
These high-temperature powder coatings for exhaust headers claim that they have a higher heat resistance than ceramic coats and regular powder coats. They also promise to offer corrosion as well as abrasion resistance. High temp powder coats come in various colors, so regarding the aesthetics, you will be sorted. They are basically an improved formula of ordinary powder coats, only that they have been designed to withstand more heat. Several car owners have tried out high temp powder-coated headers and most have expressed their satisfaction with these types of coating.
Some of the things that have been praised about high temp powder coats are their durability, ease of maintenance, and adding beauty to the headers.
For those of you who prefer powder-coated headers instead of ceramic-coated ones, go for the high temperatures ones. These will not disappoint you.
Depending on the brand you decide to get high-temperature powder coatings from, ensure that you get the one with the highest heat tolerance. Depending on the level of care you show to your high temp powder-coated headers, they can last for more than five years. Even though ceramic coatings are known to last longer, high temp powder coatings can serve you for a relatively long period.
Considering the average price of high temp powder-coated headers and their expected shelf life, you can be assured of getting value for your money. With time, the high temp powder coats on the header will be weakened by the excess temperature. And what follows is some color change and peeling. When you notice this, you should have the high temp powder coat re-applied. It however holds up pretty well.
And you enjoy all the benefits mentioned above for a long period. Most people appreciate the aesthetic appeal provided by the powder coat. However, there are more advantages.
The first is heat management. This advantage comes from a high temp powder coating. As you may already be aware, the engine produces a lot of heat. This heat spreads to the nearest parts including the engine. This heat may hinder the performance of these parts and this will affect your driving experience.
It also prevents rust from forming on the surface of the header. Other than the advantages, there are some drawbacks to getting a powder coat on the exhaust header. Secondly, coating an exhaust header is expensive especially if it is handled by a professional.
However, when you evaluate the cost against the benefits you get, it makes sense to pay for your exhaust header to be coated with powder or ceramic coating.
