exhaust manifold smoke after paint

[jpmxrider489]

I baught a forced performance manifold and decided to paint it with vht high temp paint. So after the start up it started smoking.

Should I wait and let it burn?

Can I drive the car?

Will it catch on fire?

Is this safe?

What should I do?

Wait and let it burn.

Read the side of the can, it'll tell you its normal.

OK my can didnt say anything. How long will it take?

No way to know, put it outside turn it on an grab some popcorn and a lawn chair and watch it to make sure nothing happens until its done smoking. Thats the safest way to do it. Or just take it for a drive but be careful

ok. has this happend to anyone else? I thaught I did good but I guess it was a mistake on my part.

What temperature rating is the paint and how long did you wait before exposing it to heat?? I believe you have to let it sit for a while before you expose it to heat. Your best option would have been ceramic coating the manifold since high temp paint won't last as long an will start flaking off.

Dude thats a normal thing to happen until the paint cures.

Why did you paint an FP manifold in the first place?
Was it old and ugly or something?

BTW, yes it's normal..when i painted my manifold heat shields and first turned the car on with them i thought something was burning..the smoke will not go away in a manner of minutes.
It took my car like 1 full week for the smell to go away..

Honestly is it ceramic coating? and is it rated for 2000 degrees or more? if not it is probably just going to flake off....

 

[goodbuds]

yup...check this out

top is old ceramic coating still holding strong, and if they offer this at a near by shop get it (titanium coating). its a step up from thermal coating and it looks bad ass.

yup totally normal..... I painted mine with VHT Flame proof black ceramic coating and its held up great and looks good, but I let mine cure for a few days before I used it and it still smoked a little but only for the first warm up.

 

[jpmxrider489]

I think the rating is for 650. I know that fp doesnt coat them so I figured I would try. Ill just start it and give it a bit and see hwat happens. Hopefully the color dont flake off.

 

[DSMer541]

650* is way to low.... that deffinetly wont last..... I would suggest getting some VHT flame proof paint.

That won't last long. My EM hits 650* just starting the car.

Mine is titanium/ceramic coated, with a coat of Rustoleum high-temp BBQ paint on top of that. Looks great and is holding up nicely.

For max heat insulation, go with a wrap.

heat wraps are known to crack manifolds... id stay away from it... at least thats for tubular manifold, you might be safe with the cast FP manifold.

I believe I suggested that a few posts back

no actually you didn't, ,..... you just asked what kind of paint it was, then told him it was gonna flake off if it wasn't rated for more than 2000*..... I actually recomended a certain brand of paint..... so go argue with some-one else...

and this guy recomended it before you.. so.....

For the exhaust, you get the highest you can get. Some spaceship re-entry shit.

I think I used #### degree paint and mine never did any smoke. Maybe some smell, I don't remember. I let it sit for a day or two after painting. It's been there for years, no problems. Looks great still.

I'm a little surprised, it held up better than my valve cover, which faded and flaked. The valve cover only gets a couple hundred degrees. Now for that I used ### degree brake paint.


EDITED because I may have the degree value way off. Anyway, use exhaust paint for exhaust components.
