Exhaust manifold finish?
 

What if any factory finish was used on exhaust manifolds?

Rust!

VHT Newcast paint is nice and make it look like a new casting.

Tom,
On Vermin, I used "CAST-BLAST" with a 3 Year "curing" time. Anxious to find out from his new owner, if it held up well:confused::confused:
On Minervas' Old stock exhaust system, sanded it with 180 Grit Emery Cloth & did the WHOLE thing with CAST-BLAST. "Someone"??? asked, "What did the NEW exhaust set you back"?

I used Seymour Cast Blast.
Cured in the oven.

I've used cast blast in the past and have really liked it. Just curious if they did anything with them or sent them out raw.

Used this 10yrs ago and mainfold still looks new.Snyders carrys this product

Re: Exhaust manifold finish?
 

Packard and a few higher end cars had porcelain coated manifolds years ago, but other ordinary cars all came raw cast iron that I know of. I've never seen any cars with painted manifolds from the factory.

Re: Exhaust manifold finish?
 

Th OP's question seems to be "How did they come out of the factory?" I don't know. Jack

Re: Exhaust manifold finish?
 

If I remember the judging standards I think they were just raw - maybe a light coat of machine oil to prevent rusting in the factory and until someone bought it. painting or coating seems like an extra step and cost that Henry wouldn't approve of.

Does anyone have a good pic of a manifold painted in cast blast? I will soon be painting my new manifold and am interested in how it turns out. Says it has a wrinkle finish that im not so sure on.

Re: Exhaust manifold finish?
 

Many years ago, I painted my exhaust manifold with stainless steel in a spray can. Held up very well. Sorry, don't remember the Brand Name. Google..

Re: Exhaust manifold finish?
 

I used VHT's Flame Proof Satin Clear, 1300° - 2000° and shot over a clean brand new manifold with (2) light and (1) medium wet coat. The highest temp in clear I could find.

Sorry, Double post.

Re: Exhaust manifold finish?
 

Geez...been so long I don't remember but I think I used a Por 15 high heat product. Looks as good today as it did in 2003.

Re: Exhaust manifold finish?
 

My CAST-BLAST wuz NOT wrinkledy! (sp?) I dreamed about doing the block with it & a FAUX Woodgrained Head! (Like the Cigar Store Indian)--LOL--Or how about a Woodgrained Fan Blade?

Re: Exhaust manifold finish?
 

Bill, the Cast-Blast is holding up very well. I almost asked you this same question. I don't know where to buy it in the Bay Area. Commies won't let us have any "dangerous" products. When I get my two bladed fan I will wood grain it to look like some white pine of maybe I ought to go with Hickory?

Re: Exhaust manifold finish?
 

Can you guys post pics of your manifolds that are painted with cast blast and the clear protectant? I'm trying to decide what to do... I appreciate it!

Re: Exhaust manifold finish?
 

I'll take a few pictures for you tomorrow. Just finishing one up.

Re: Exhaust manifold finish?
 

I had my Victoria manifold porcelain zed cast iron, fifteen years ago and it still looks like new cast iron today. it is pretty pricey but it lasts. I used to remove my manifold and muffler every couple years and repaint them. not anymore.

Re: Exhaust manifold finish?
 

About three years ago
And yes I know...the intake is white. I like it like that

Re: Exhaust manifold finish?
 

Is that cast blast? Looks more like the high heat BBQ paint. My current waffle manifold is painted with that stuff and holding up great but my new repo exhaust manifold id like to keep the cast look to it.

Re: Exhaust manifold finish?
 

Very good eye there SeaSlug.
Yep, high heat BBQ paint, works great, lasts long and won't break the bank.

Re: Exhaust manifold finish?
 

I wire brushed the rust off a used manifold and painted it with Cast Blast . I let the paint cure on the shelf untill I was ready to use it . The manifold still looks purdy good after 12 years . I figured that there was no need in spending much on manifold paint . In some cases the manifold will need replacement before the paint completely fails .

Re: Exhaust manifold finish?
 

Anybody use "Calyx Manifold Dressing"? Saw it online and wondered how it compares with other paints mentioned in this thread:

Re: Exhaust manifold finish?
 

Here is a couple pictures of one I just finished using cast blast.

Re: Exhaust manifold finish?
 

oooh shes purdy. Im sold! How did you guys cure it? Ive got all the time in the world as its Feb in central IL. So wont be messing with manifolds till i dont need to wear gloves. Time and letting it sit in a warm house or does it need to be cured in an oven?

Also is 1 can just enough for one manifold? i have 2 manifolds i need to paint and unsure if one can will be enough...

Re: Exhaust manifold finish?
 

You can probably do two manifolds with one can. It'll be close.
You can cure it in an oven or a barbecue grill. I use a propane torch and play it over the manifold while checking it with a laser thermometer. You have to get it to at least 400 degrees to cure it. If you get up closer to 500 it will begin to smoke some.
I did my first one in the oven at home. Glad my wife was away on a business trip for a few days. Really stunk up the house.

Re: Exhaust manifold finish?
 

Noted on the oven haha. Hmm i got an old bbq grill that can be used. Has anyone found this stuff in a store? I plan to check Big R, TSC, Farm N Fleet, Ace, and some of the auto parts places. I coulda sworn ive seen it somewhere.

Re: Exhaust manifold finish?
 

Nothing was used from the factory. It was plain cast, hence the use of the "cast blast" coating to simulate the look of just cast iron.

found this article using slip plate - looks nice. Not sure on the longevity or if everytime you touch it comes off on your fingers...

Re: Exhaust manifold finish?
 

I used cast blast on a manifold last summer, here's a photo. It's not a wrinkle finish. I haven't cured it in any way yet, I just put it on the engine which I'll be getting started in a few weeks.

Re: Exhaust manifold finish?
 

IS that a special manifold that is missing the bolt holes for the intake? Looks great otherwise

Re: Exhaust manifold finish?
 

Looks like tape on the area, though I'd paint everything.

Re: Exhaust manifold finish?
 

Yep, masking tape painted with Cast Blast hiding the holes.
