Just a tip for people that think about powder coating. I purchased a cheap kit from easton supplies,just to experiment. Then realizing that I could not afford one of the oven or expensive heat lights.So I build a medal box the size for my headers ,then having a round kerosene heater,removed the top added a round tube the size of the heater down into it. This home made oven heats up to 450 degrees within 20 minutes and is cheap to operate,also I can do it outside. Works great. MiMax

I thought header coatings were a ceramic and needed to be heated higher than 450? What kind of coatings are you using. I've got an $800 set of Stahl headers I sure would like to get coated. Bob

your right bob. powder coat will burn off.

Baddbob: My guess is in asking around that you've gotten pretty much the same answer I got when I wanted to spiff up my headers. Paint burns off, powder burns off, and chrome turns blue. Ceramic is the best known alternative at this point. You'll pay dearly for it (mine were $300 from JetHot) but it looks good and it holds up.

MiMAX: In your setup do you have a way to isolate the flame from the oven? I've heard that gas ovens should not be used because of potential fire/explosions resulting from the powder coat curing fumes. I know I can really smell these fumes in my shop when I run my electric oven. I don't know how explosive they are...but glad to hear you are curing yours outdoors.

Since the box is a rectangle,to get the the heat to the outer ends,I drilled two 1/2 holes in each end. As this thing heats up it allows the heat and the fumes to exit each end which also evens out the heat. by its design it is an up flow draft,just like a chimmey. MiMax

Could you post a picture. I have a power coating kit also and have not used it yet because I don't have an oven....but I have a kerosene heater....

Not the fumes the powder itself, if there's enough to burn kind of like a grain elevator explosion.

There are various High temp powders Eastwood has them, that while they cure at 450 degrees are good to 800-900 after cure.

Columbia coatings also has a ceramic coating that sprays on in a water soluble spray cures at 500 and is good to past 1000 degrees.

Ordinary powder coating will burn off High temp powders wont.

Here is the site to go to read / study about header coatings.

Also don't overlook the other coatings for engine parts and various other car parts.

I have been following this for about 8 years and will use them when I get a garage / workshop. (SOON I HOPE). I hate my **** stored all over the place.

Enjoy.
