High temp coatings
I recently acquired a really nice pair of original Fenton headers (Thank You 40fords!). Just had them lightly media blasted and will be painting them gloss or flat black. Now I know that there are a ton of high temp products around these days, in my youth the go-to brand was VHT, maybe still is. Anyhow, there are other brands, ceramic varieties, and so forth. Just wondering if there are any recommendations for a product RECENTLY used by someone. I also see some high temp primers offered, important to use? On my '32 Highboy roadster with an open engine compartment, I had the headers ceramic powder coated and they have held up great, but I am kinda looking for a rattle can solution here. Thanks guys.

Re: High temp coatings
Check out the Cerakote website - for their high-temp ceramic coatings. I've used them for headers on a variety of race and street cars. The key is for the media blasting to be done correctly (and don't touch the material with your bare hand) - and then put them in a BBQ and bake the coatings on at about 500 degrees. Once you do this, the stuff is pretty darn tough.

Re: High temp coatings
I've used the Rustoleum High Temp paints on the exhaust manifolds in our "55 tbird and '67 mustang and the Red's headers in my '36 coupe- very pleased, especially on the cast manifolds that like to bleed rust even after sandblasting. The tbird manifolds are several years old and still look like I just painted them. Use the primer and follow the curing directions.

That looks real good. Are those bungs on the head pipes for A/F sensors?

Having both O2's and EGTs gives me what I need to tune the carbs. I use the O2's the most as I'm not running these on a boosted engine (where EGTs become all the more important). |

Re: High temp coatings
I hate to be this guy... but whatever paint you use will burn off. Most exhaust manifolds will see up to 500 degrees over time repetitively. It will break down. They might hold up for a bit.
Paint them with a good paint but don't be surprised in a yr or two if it's gone. The fentons will still be cool! |

The High Temperature Rustoleum won't. We have a '55 T bird with the original cast iron manifolds--sand blasted and primed and painted with the High temp paint six years ago. We drive it quite a bit and those manifolds still look like new. |

Re: High temp coatings
I’m using Jet Hot in North Carolina to coat my exhaust manifolds. The advantage is that it’s a thinner coating so it isn’t likely to crack off. It comes with a lifetime guarantee. From what I’ve been able to gather it’s superior to cerakote. The POR product I tried didn’t work rust stains one month later.

Re: High temp coatings
My tube headers are coming back tomorrow from Jet-Hot had they done at the place in Ga but they started to peel so I sent them to Jet-Hot.They are set of total tube headers with a 3 inch collector and I don't want them to rust out.Trying to remember the guy in Oregon that just passed away did them.A flathead man.I'll think of his name later.I've tried all kinds of paint on my other cars and nothing holds up

That message is likely telling you that the "jpg" image is too large for a FordBarn download. If you e-mail that picture to yourself and then use the 'NEW' e-mailed image (save the new image to your computer), I'd bet a quarter that it will post! PLEASE let us know how that works-out! DD |

When I was building my former 35 Coupe I know I was certified insane and "over the top" in my approach ... I just followed the leaders back in the 30's like Rolls Royce, Cadillac and Duesenberg and had my Fentons finished in black Porcelain. Five years+ and not a flaw in the finish. |
