Great information.

I still say a light rust is correct. Glass bead, vibratory tumble, and let nature take it's coarse. I'm in the 1% .... Rust is right.

Thanks for the pic Mike.

I always say, &quot;Pretty is not always correct&quot;. Some of the components are painful to look at, but very correct for a restoration. [img]<<GRAEMLIN_URL>>/scholar.gif[/img]

Way too many cars have been done with pretty painted manifolds, it's becoming the norm and what is expected today, Sadly, incorrect.

And it's becoming boring [img]<<GRAEMLIN_URL>>/dunno.gif[/img]
The light rust on a Trailer Queen will continue to look fine, when you take moisture out of the equation. After that car was run a few times it looks even better now, and just a hint of orange left behind.
Stop and take a look @ SLS 6.5 [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

But guys look at Dicky's original first post. He is not asking what is the correct proper factory set up for manifolds.

He asked

&quot;To all you restoration shops &amp; members;
What is the best method to treat cast iron exhaust
manifolds to prevent rust and maintain a raw cast look,
(without burning off)&quot;

Paint them or treat them = modification.

Return them to &quot;as cast&quot; = Restoration.

Apples and oranges...clear as mud right? Do what makes you happy and enjoy your manifolds. Life's too short..
