Jet-Hot header coatings
I just got a quote of $279 to Jet-Hot coat my headers. I am going to get the new Sterling color. My question is:
1. What experiences has anyone had with this coating?
2. They claim that the under hood temp is decreased by ~40 degrees, is this true?
3. Are you happy with the results?
4. Is it durable?
It’s got to be better that taking my headers off and painting them with VHT paint every few years. Please give me your feedback on this.
Thanks Guys/Gals

Re: Jet-Hot header coatings (theandies)
I think that is the best thing you can do to your headers. It will outlast any paint and will help with engine temps. Make sure they coat the inside as well as outside.

Re: Jet-Hot header coatings (theandies)
I recently got a set from them. Haven't finished the install yet. I wish I had taken the extra time to get the uncoated headers in advance to clean up the dings and press marks on the tubes, as well as the weld and port inconsistencies on the flanges. The headers look fine, but they could look a lot better. In other words, Jet hot takes them as they come from the manufacturer and coats them. That's it. If there's a flaw you are stuck with it.

Re: Jet-Hot header coatings (Never Finished)
My headers are only 2 years old so they are in good shape. The quote is for inside and out. Thanks for the feedback. I know what I am doing this weekend.

Re: Jet-Hot header coatings (theandies)
Here's a pic after 5 years use. The first 8 inches have lost their shine. That actually happened almost right away because I was running too lean. The remainder of the headers all the way to the collector look like brand new. I called Jet Hot about it, and they said that even though I burned the shine off, the coating is still there and they will warranty rust or burn through for life.
I don't know about reduced temperatures because I went from the cast iron log right to the Jet Hot coated headers.
PS-you might want to talk with them about a package header and coating deal. Mine were $305 for the headers and the coating delivered to my door.

Re: Jet-Hot header coatings (biltogo)
I have had the same experience biltogo had ,loss of shine . But all in all the coating is great and very durable inside and out . Not so sure about underhood heat though .

Re: Jet-Hot header coatings (77Dream)
I think it does help keep the heat down. The coating is supposed to reflect heat so the heat should be kept more inside the header tubes. I know my non coated headered formula feels way wamer under the hood than my coated header vette runninng somewhat similar set ups.

Re: Jet-Hot header coatings (theandies)
The still get freaking hot tho'. I have a perfectly round scab on my pinky knuckle to prove it!
Chris
ps, mine also lost the shine. use neveral dull or someother impregnated cloth to clean stains before they become chemically attached to the ceramic and they will stay in like new condition for years.

Re: Jet-Hot header coatings (theandies)
I got a quote from Jet Hot also, $399 for Hookers. Got the following from Jegs. What's everyone's opinion? Cost, quality, name brand, etc.. Are these real Jet Hot? Says they are! THANKS!!!

Re: Jet-Hot header coatings (hudman)
Mine have worked ok. I had coating failure after the second year, but they recoated under warranty. They get hot as hell and have more contact space to radiate heat, so 40 degrees cooler may be optimistic.

Don't buy them because they "reduce underhood temp." Period! Buy them because the finish is permanent and you don't have to pull them all the time to paint them. :nopity

Re: Jet-Hot header coatings (theandies)
The temp reduction is over uncoated/unwrapped headers. Not sure if the 40 deg claim is accurate but it does seem to help when I compare my cars. No if your talking 40 off the surface temp of the header, not sure if you will feel much of diff from a drop from 840 to 800.
