- Mike Phillips from Phillips Hot Rod and Customs goes over how to paint a set of headers for his race car with Eastwood's Internal Exhaust Coating. Great method for protecting the inside of headers, manifolds and exhaust systems.

Eastwood High-Temp Internal Exhaust Coating reduces under hood temperatures and extends the life of exhaust system components
Thermal coating withstands up to 1800 degrees F
2'-long, 360-degree aerosol extension nozzle for easy application
Works with both new and used exhaust system components
Use our exclusive formula to coat the inside of exhaust system components to trap the heat inside the tubing, thereby lowering under hood and under car temperatures. Great for headers, exhaust manifolds and more!
Since 1978 Eastwood has been supplying products to the people who want to do the job right. Eastwood offers a complete line of hand tools, welders, plasma cutters & accessories, metal working tools, powder coating supples, paint and paint guns, specialty paints and hard to find products, all for the DIY-er. Eastwood has all the tools and supplies you need to restore your car, truck or motorcycle.
why not test the coating? any gearhead would assume that will just burn off in 10min, plus id like to see the heat transfer from a pipe coated vs one that is not.
+trevor shannon It will not Burn out. Its rated for 1,800 Deg F. If your exhaust is running hotter then that you better get out of the car... Stay tuned for info on a test. Ill take care of it. Trust me IT WORKS!
The exhaust temp near the block surely exceeds this value ! And what is the purpose of coating ? It will be soon coated with carbon deposits so...
There are several good reason to coat the inside of a Manifold or header. Corrosion is one major reason. Headers always rust from the inside out due to the bare steel. Coating the inside will require a material that can withstand the temperatures. The thermal barrier is also great. You could help prevent a cast manifold from cracking for one reason. The main reason I like it is because it keeps the temperature of the exhaust inside the exhaust instead of dissipating throughout the system and heating up the components under the hood. Thus lowering under hood temps. The build up of carbon in the tubes will not matter. The thermal barrier is still there. It will help prevent the dissipation and absorption of heat into the metal.
@@phillipshotrods Lol that's what spray paint says too 2000 degrees my ass
@@steve5912 GD bro, just believe your opinion like it's a fact and stick with it huh? You vote for trump too? Loser.
Eastwood should make a clamp type mount that works like a hone without the actual grinding pads that mounts before the end of the tip of the 2' hose. that way it keeps it centered and it still flexes for the turns
A little ingenuity with cutting a disc of Scotchbrite pad and you just saved yourself some cash.
codysett1 came here to say the same. 3 thin wire guides would keep it perfectly centred.
I used 2 milk jug caps to keep it centered in the pipe. Drill the center to the size of the 2 ft.tubing,spaced 6" apart and pinch a piece of masking tape to each side of the caps,to keep them in place. Before you start spraying,rotate the spray can both clockwise and counter clockwise to unkink the tubing.
how nice you get great products out there, lucky folks.
How much does it reduce exhaust tube temperature and by what testing method... contact thermometer or infrared thermometer?
Need to get one of those laser thermometer Gauage
What about coating the outside as well? I’d love to see a before, interior and interior with exterior coating.
Can you do this to exhaust pipes that have already been Cerakote on the outside????
How about to prevent blueing on a thunderheader exhaust for motorcycles? Would this help?
Where is the before and after video on the temperature with a laser temp gauge?
Probably best done on virgin metal tubes. Not sure how one can absolutely clean the inside of tubes once exhaust gas runs through them.
Can you combine it with external high heat paint???
Yes
Would this help prevent blueing on Harley headers?
Can you use this ceramic on Mufflers, internally.
a ceramic type coating ?
How many cans should I use for a set of headers !
it depands if you have shorties mid lenght or long tubes
Can this coating be added to the outside of the beaders?
We offer High Heat Paint that resists temps ip to 400F: www.eastwood.com/silver-hi-temp-coating.html
1400F.
@@eastwoodco why wouldn't a person want to coat the outside also with this same product? Why do you suggest a different product for the outside (hi temp paint)? Because the product in the video would be seen burning or flaking off if applied to outside?
I need that extension nozzle for painting inside a-pillars and rockers on my restoration product. Can I purchase the nozzle separately?
+Andrew Miguelez I would like one to spray rust convertor or oil in tight places like doors and rocker panels.
+57WillysCJ Yes! precisely.
The old school under $20 solution is to thin your paint/coating and put it in a pump up garden sprayer. Take the tip off the sprayer and up it on a long piece of hose. Set the tip to spray a cone, stick in the frame/piller/rocker, and go to town.
to bad you can't coat the entire length of the tube with that
short hose I guess the best way would be to dip the whole
header in a vat of the coating, but who's going to offer that service ?
The tube is 24" long. He stuck it in from each end to get full coverage.
Eastwood Company. Thats what she said ;)
Will wrapping the outside still be beneficial?
No, heat wrapping kills headers. There's a reason header manufacturers will void warranty if you put that on.

@@jasonhuber3236 Great info in the link
It will trap moister and rust out fast
any follow up of testing this out?
I'm sure they will delete this but I can give my experience with more than a few of these DIY gimmicks. They didn't work in my v8s10 race truck. You have to get the stuff so thick to stop heat transfer you will end up spraying a gallon of the stuff in each header by the end of the job. Might as well pony up and have them ceramic coated by that time.
The only thing that finally quit cooking my feet in my truck was swapping to stainless steel headers and wrapping them. We wasted so much money trying to save money with mild steel headers I should have just ponied up from the start. Granted I never had any ceramic coated but my mild steel ones finally rusted out. By that time I have outgrew them and wanted some better designed stainless ones. Since I didn't have to worry about rust at that point I just wrapped them.
Ah I see thanks!
didn't explain if the paint line goes all the way in to the header tubes or not - assume 2 feet?..
I never thought that you needed to coat the inside of stainless headers to make them last longer. Thanks for the tip and I will start using this spray from now on. Some shops have been installing a flexible mesh at the collector to prevent rattles. It would seem to me that this coating would make that mesh last longer. I have seen this mesh used on the Schwartz performance exhaust videos where they install a clamping mechanism on the collector and use oval 3 inch stainless exhaust pipes to gain ground clearance. Question, Have you ever tried installing the flexible stainless mesh on headers and used this coating on the insides? Does it help to prevent burn out on that mesh material? Here is the link where they use that mesh that I am talking about if you do not know what I am talking about. th-cam.com/video/WmdOSmaTtGY/w-d-xo.html
How long does the coating last?
+Dan Mallery If you do your prep work correctly it should last forever. Its good for 1,800 deg F. Top of the line super expensive coating that you have to send your parts out for are rated the same...
External thermal ceramic coating is the only way to go.
lol im like 10 miles away from you
It will just burn out
+BIGBO1988s10 It will not Burn out. Its rated for 1,800 Deg F. If your exhaust is running hotter then that you better get out of the car...
