I understand most use the Eastwood High Temp Coating paint to give the sandblasted exhaust manifolds a raw, new look that lasts for quite a while.

Could the exhaust tubing (after bending, welding, etc) be sand blasted and the same Eastwood coating be used to give a new, raw, bare steel tubing look, that will last? Or is there something else that will work better, last longer on exhaust tubing? Thanks

Beautiful smooth finish every time.

I was wanting a new, raw steel look (coating) for the exhaust tubing. You know, what a brand new exhaust system looks like before any rust.

That Eastwood manifold paint makes the manifolds look like new raw cast iron. Was wondering if it would make the exhaust tubing look new also. However the tubing doesn't get as hot as the manifolds nor does it have the expansion and contraction cast iron does. Was wanting to know if anyone has used the Eastwood manifold paint on exhaust tubing? If not, what is used to get a lasting, new, raw steel, look on tubing. Thanks

What year are you working on? The photo I'd provided earlier is an accurate restoration of a '40 system.

It's more of a custom application. You know, places takes a stick of that aluminized (or mild steel) exhaust tubing and bends to fit with one of those hydraulic tubing benders. Where there is a weld, expansion, or sharp bend the aluminized coating is compromised and will rust and discolor. Sometimes very quickly.

Let me try and reword my question.
Has ANYONE taken ANY of these cast iron exhaust MANIFOLD coatings (Eastwood is a popular example) and successfully coated steel exhaust TUBING?
Whether or not the exhaust tubing is one off custom bent, or a 1000 made for a specific motor and cassis, it is all the same tubing.

I have explained that cast iron (manifolds) and (mild) steel (tailpipes and exhaust pipes) have differnt properties, expand and contract at different rates. That these High Temp manifold coatings may NOT work on exhaust tubing. Maybe, just maybe someone has expermited with these manifold coatings and found out they will work perfectly on something else. THAT is what I am trying to find out. Maybe to save me the time, $$$, hassle, to find out if will work or not.

As far as using the flat black high heat powder coating process you mentioned, that is my "Plan C". You are absoulty correct in stating the toughness, long lasting, visual durable, of powder coated exhaust systems!

Thanks again.
