Spray painting exhaust manifold or headers - high temperature ceramic paint
Вставка

- Applying and curing 2000 degree Rust-oleum high heat paint on my Saturn s-series cast iron exhaust manifold. Other paints are VHT Flame Proof, KBS Xtreme, and Thermo Tec Hi-Heat to name a few. Eastwood carries a product called Fox Body, Painting is much cheaper and easier than ceramic coating but may not last as long. I will report back on the condition as time progresses.
You will see that first I applied the high temp primer, then the paint which in my case produces a nice silver finish.
Prep work is critical. I cleaned this manifold with a wire brush on a drill then washed it in the sink with soap, then cleaned with acetone before painting.
Unlike the 500 degree paint I used on the intake this 2000 degree paint requires a curing process which can either be conducted on the vehicle or in an oven. I used the oven. The curing process shown in this video involves heating the parts to increasingly higher temperatures with a cool down time between. This tempers the paint to bring it up to full specifications.

Dont use an oven that you plan on using for food.......because most people have a separate oven in their homes for accelerated paint curing purposes.
I think hes just saying that for legality reasons, Don't want to be a victim to sue hungry ppl
I am not worried about using the home oven, but I have a wife and well..you get the picture..happy wife happy life.
It holds up great as long as you use the primer and bake the parts. I did headers with just the paint and it needed re done in less then a year. Used the primer and baked the pipe and its still good 3 years later.
Does it have similar characteristics as ceramic coating? What if I used the 2000 degree primer for my pre turbo headers (not inside) and then spray the ceramic coat instead of the paint? Do you think you need primer for ceramic coats?
I can't find the primer anywhere in stores these days.
Its like 3 years already. How does the paint hold up?
Nice job on the video with the details and step by step process. The manifolds look almost good enough to eat :>)
Great Job!
Thanks!
Especially with porous metals (cast iron & cast aluminum) *preparation is critical* for a lasting finish.
*A wipe down with acetone after degreasing is an excellent preparation*
Even chrome and stainless steel exhaust pipes develop the tempered "rainbow" after a time;
If you keep up on simple preventative maintenance (cleaning, touchups, being careful of handling, etc.) it will last for years to come.
I've found that using many coats, and using a Q-Tip to apply to fasteners _after_ the part is installed, then using the high temp "clear" is also key- and "curing in place" (part attached) with a propane torch works very well to flow the ceramic properly.
Metals, plastics, rubbers, and woods- all have a common enemy: Oxygen. It works like a chisel- to break down the matrix of the molecules, attack them, and attach to them. (oxide)
A simple coating is all that's needed; coloring is merely aesthetic.
HUBBABUBBA DOOPYDOOP You're right, clean, clean and clean, prep before painting is most important. I've welded a lot of aluminum and cast iron/steel parts over the years and I try(when time allows) after it's as clean as possible to bring the part up to 150℉ or higher for a short time and with a crap casting you sometimes see the oils leach out. Either welding or painting you hate to see crap coming to the surface and ruin a nice job. Good comment.
Any Updates on how this held up???? I'm about to do it to my snowmobile pipe
could you post 2020 video update ? How long did that last?
would be great to get an update on how the paint held up.
What about doing the same thing to the internal of the manifold? Since it heats up from the inside.
How has that paint held up over the years?
I am going to be painting an exhaust manifold myself soon, that's why I ask.
is your paint holding up. maybe another video to show us?
so what if i dont have an oven ?? i read in the instructions it says (item off of vehicle) and another is (item on vehicle) does it mean that i can use one of the methods?? or i have to do both ? cuz i have the same paints right now
I thought I was the only one who used my oven for car parts hah
Is there much heat dissipating from the manifold? Is it reduced?
I spray paint with the high heat resistant stuff my entire exhaust system including the muffler and as well many welds of the undercarriage . This paint protects the metallic surfaces from rust really well.
at 3:20 in the video the instructions say you can idle the car for items on the vehicle so why not do that??? those cast iron headers will bake themselves once they are on the car i dont see a reason for putting it in a oven
Because the engine wasn't in the car.
good, good
Could I use UV to cure this instead of heat?
👍👍👍
It's still working ?
How did this hold up over time? Any discoloration or did any of it burn off?
thats what i wanna know!
2008gsxr1k same here!
Jordan Young me 3
Mike p me 4. But apparently he doesn't like to answer questions.
Eric Ver Linden Some people don't have notifications turned on. I have videos I made and end responding months or even a year later when I stumble on the comments.
Btw do not put the manifold in a microwave lol
+Nicanor Carrillo - BOOM
Does this paint actually STAYS or PEELs off??Its very hard to find quality heat resistant paint that doesnt peel off after few weeks!!
Tomas Tamulis I had that problem too. The only thing that stays longer than a year on my motorbikes exhaust is paint for stoves and bbq's. It is only in matt finish though.
I got a problem with this method, i can't stick my engine in the oven. HA
best to get it media blasted
there is nothing out of a spray can that will hold up
andy grundman you are wrong
I only use Rustoleum anyway >:0
junk. wont last
robert tallman I agree. There was still rust all over that.
Why tf would you paint an exhaust manifold to begin with? No paint will hold up for very long just leave it the way it is no one cares about what color your engine is
