Painting Exhaust Manifolds
 

In the process of correcting parts on my 69Z project that I picked up in midrestoration. The exhaust manifolds are already painted but much too dark for my liking. What are your thoughts on another coat of the correct color. Would that result in issues down the road. The car is well worth doing right, low mile AZ car, numbers matching with BS. Leaning toward sandblasting them and starting over.

I'd go with your instinct! https://www.yenko.net/ubbthreads/imag...mlins/flag.gif

Re: Painting Exhaust Manifolds
 

Have them FLAME SPRAYED (search on google) to eliminate future rust from starting...and then spray with 1200' VHT cast blast, to give them correct cosmetic look!!!!!!!

Re: Painting Exhaust Manifolds
 

When you mean "painted" do you mean painted orange or coated in one of those eye-soar eastwood coatings? If the orange is your worry, then let the paint burn off, if the coating has you down, another vote for sand blasting and starting over!

Re: Painting Exhaust Manifolds
 

Thanks for the input guys, kinda what I figured. I keep taking steps backwards to correct things. Its frustrating having to take it back to square one but for the end result I want I don't want to cut corners and regret it later.

thanks again,

Dave, Are you going to be documenting the restoration with photographs and posting for all of us to see? https://www.yenko.net/ubbthreads/imag...ns/naughty.gif https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Re: Painting Exhaust Manifolds
 

The past several restorations as well as my L78 exhaust manifolds I have sent to Central Connecticut Coatings 860-528-8281, they blast them and coat the inside and outside they come ot like NOS even though most of the GM manifolds I put overspray on them. Good luck.

Re: Painting Exhaust Manifolds
 

I sent my manifolds to the new Jet Hot factory in PA. Their cast gray looks excellent. Inside and outside coating plus shipping was $250.00.

I had Jerry Macneish do mine and he included the Cast Blast spray and they still look awesome after 6 years

Re: Painting Exhaust Manifolds
 

Jim69Z, When you received your manifolds from "Jerry MacNeish" were they already coated with "Cast Blast spray" ????? If not how would you describe the look as returned ??????

Re: Painting Exhaust Manifolds
 

Chuck, From what i can remember they were basically had a silver bare metal look and they were not sprayed at all with the Cast Blast and i know on his website he has some after pics from the reskinning process.
Hope this helps

I had a pair done by Jerry. Here's a before and after shot that I took when I sprayed them.

Re: Painting Exhaust Manifolds
 

Yes I plan on photographing and documenting the process as well as posting it here soon as I get some time. Hopefully in the coming week I can start a thread. Right now working a lot of overtime which is good, because I need $$ for parts, but leaves little to no time for working on the car. Currently I am going backward, removed the front clip, eng/trans in order to correct some minor issues. Of course the further I get into it the more "issues" that pop up. Now I have to strip and repaint some of the firewall, too many runs even for that "factory correct" look. My plan is to not go with the "overspray" look, I appreciate it but it's not for me, especially since the paintjob is already done without "overspray." Guys thanks for the input, even more confused now https://www.yenko.net/ubbthreads/imag...s/confused.gif. Another question, will any of the above processes compromise the threads for the smog system?

Re: Painting Exhaust Manifolds
 

Jerry did mine seven years ago, and they've never changed at all; they'll never rust.

Hey Dave - howz 'bout some more particulars on your Z? https://www.yenko.net/ubbthreads/imag...ns/naughty.gif

Re: Painting Exhaust Manifolds
 

Just the basics for now until I talk to the original owner.
Phoenix car from day one, supposedly sat on a lot for nearly a year and bought to race. Number two owner should be out of prison by now. Three owner car prior to me, 33K miles, not cut up too bad considering it was raced, few holes in the firewall, tunnel was cut up for an auto, dash was cut up some, entire car was painted black, right over the vinyl top, as well as the interior, door panels and all. Daytona Yellow, white top, white stripes (still not sure it wasn't a black stripe car, but that would have looked pretty odd) white hounds tooth, has aftermarket chambered exhaust, original engine, heads, intake, exhaust manifold, carb, 4:10 rear, M21 is not original, deteriorating buildsheet. Restoration began approx 5 years ago, eng rebuilt, car was painted, upholstery done and a lot of parts tracked down, previous owner had too many balls in the air to finish it and finally needed money, I have been after the car for about 5 years now. Thats it for now, more to follow.

I've had the pleasure of seeing it in person and it's https://www.yenko.net/ubbthreads/imag...mlins/cool.gif

Daytona Yellow with a White V-top and White Houndstooth will be AWESOME!

And it would have had black stripes. https://www.yenko.net/ubbthreads/imag...lins/smile.gif

Re: Painting Exhaust Manifolds
 

They will never rust because in MY opinion they have been "flame sprayed" with ALUMINUM giving them that whitish/silverish color.......The aeresol cast blast paint cosmetically covers the new "skin" and makes them appear more natural...............

That's correct - they're plasma-sprayed with about .005" of aluminum as a moisture barrier.

Re: Painting Exhaust Manifolds
 

I thought it had to have black stripes. Can't find the link with color combos now, thought it was on NastyZ28. Kinda remembered you had to have black stripes with DY. It was already painted with white stripes, I will probably leave it that way for awhile. Should drive all the Z28 experts crazy, it will make them happy pointing out that it is wrong.

Re: Painting Exhaust Manifolds
 

Chuck,

I'm guessing I can find a place in Phoenix to have them "flame sprayed". Anyone done this in AZ? Any idea of the cost?

thanks,

Dave

Re: Painting Exhaust Manifolds
 

So far I am unsuccessful in finding anyone to "Flame Spray" my exhaust manifolds here in the Phoenix area. Has anyone in the local area used this process?

thanks

Sand blast them clean, take a light grade of sand paper and strike the sharp texture off from the sand blasting. Then get yourself a couple of old T-shirts. Have a good local parts store order in a exhaust manifold dressing called Calyx rub it in to the manifold and rub and light buff with second rag. When you start the car it bakes in. The nice thing is if you like to keep them fresh, it only take a few minute when your detailing your car. It looks like factory
cast iron.
