What do you think about this Ceramic coating?
Hey everyone, So I wanted some input and opinion on this coating I had done.
It was done on a brand new down pipe and exhaust manifold and is ceramic coated, the car was driven 5k miles and sat in a garage when not driven. I do have a vented hood and washed it maybe 3 times without the plastic piece that you can attach to it. Just couldn’t believe it rusted like this on the base and scrapes so easily when dropping it in. Any replies are greatly appreciated.

If im seeing right thats a bolt running through the exhaust manifold? Get a stud/proper nut setup and replace it if so.
Im not to knowledgeable on ceramic coating but something doesnt look right there.

It's the material used in the manifold. Looks like a mild steel flange (which is common - due to it's strength vs. stainless steel). Mild steel rusts. Heat accelerates rusting.
Scrapes happen if you're not super super careful with the pipes.
My question is what brand of ceramic coating was it?
You can always have it removed, media blasted and re-coated. Goodfella supposedly has a good line on a good ceramic coating. I prefer exhaust wrap myself but whatev.
p.s. the bolt is funny.

if it is coated it was not done right or its very cheap...A guy I work with did a manifold about 2 years ago maybe a little longer.....Just had hios car in the air the other day and it still looks like it did when we put in on.
Coating it should greatly increase its protection against rust as well as look good and keep heat in the pipe. IMO yours looks more like it was hit with some high temp paint.

thanks for the input everyone, ill read about jet hot,
yeah i know the bolt is funny, i dont remember why i did that when i took my motor out, but its back out so im going to be cleaning everything up and painting the engine bay.
The shop I had the coating done said they would clean it and do it again for free, but I just feel as though it will happen again so whats the point.
the person who coated it did tell me what grimple1 said about it being a mild steel flange, I just dont understand how rust would happen if there was a coating over it that should prevent it.

+1 for Jet Hot. I've had a few downpipes coated by them, the stuff is BULLETPROOF.
One downpipe I did I decided I wanted to remove the coating from the flange surfaces to make a better ground for the O2 sensor (you can tell them not to do that, I forgot
). So, I brought the downpipe over to a wire wheel on a bench grinder, worked on it for a while, NOTHING. It didn't even TOUCH the ceramic coating. Now, a wire wheel on a 3/4 hp bench grinder will remove damn near ANYTHING instantlly, I was shocked it didn't work on the coating!
I had to use the hard stone on the bench grinder, and even that took a good amount of work!
Get Jet-Hot 2000 coating on it, you'll be good to go. I'm not sure if there's any coating that would work on the hot side of the turbo itself, though - that just gets insane hot. A heat shield/turbo blanket is best there.

While you're at it, it might be interesting to see if Jet Hot can use a lighter colored coating such as silver or white. I suspect that those colors would further reduce the radiant heat transfer from your exhaust and keep the engine bay cooler than the black coating. At the very least, it would be a good question to ask the coating guys if you're you're going to have the parts re-coated.

they make a black and a gray color for the jethot 2000. there are other colors but they only go up to like 1300F --- which is way too low for a rotary. there's also an "extreme sterling" that is 1700F. Again it's possible that this is too low also .. . ..
