Swain Tech is the industry leader, by far.

WHite lightening your hotside, exhaust manifold, and 02 housing. THermal barrier coat you LIC pipe and UIC pipe. You can also put a coating on your intercooler that will make it disperse heat faster, with the side benefit of making it stealthy black.

 

I know that. I never said all corrosion is rust. Rust is corrosion. Joey is saying it is not. His example of teeth and coke corroding enamel is a different definition of corrode, meaning to eat away or breakdown of the surface. Corrosion occurs to all metals. Rust just happens to be what we call it when it happens on....as you said Ferrous metals. Corrosion on aluminum can be black or white in color. On copper it is green (think statue of Liberty) Believe me I see it all the time on Aircraft. I know more about corrosion and corrosion control than 90% of the people out there. How about how carbon fibre can cause horendous corrosion of metals? Ever see that? Do you know why? How about how corrosion occurs between the anodic and cathodic potential of difference in metals known as galvanic corrosion?

 

I never said you did claim all corrosion to be rust. I said you and Joey were saying the same thing and then clarified it for those users who were curious to know.

Yes I am familiar with may aspects of carbon fiber (including it's electrical conductivity, which I have taken advantage of in the past) and that it is in many ways "metallic" itself and can react via to other metals via galvanic corrosion. Most metals have some form of carbon mixed into them for various purposes, especially stainless steel. Many people are unaware of this and think of carbon fiber as a form of "magic fabric" and don't really know what it is, they just know it's strong, light, expensive, and cool-looking.

Listen man, I do not profess to have your knowledge, and am not trying to start an argument. I was just saying that perhaps you misunderstood Joey who likely did not realize the difference between acidic corrosion and galvanic corrosion, but his analogy probably worked for most people anyway. Most evom users are not familiar with the way a "more active" metal will corrode when in contact with a "more noble" metal in instances where there is direct contact, especially in the presence of moisture. And even if they were, they aren't likely to have access to find out which is the more active or more noble metal so they wouldn't even know which one to coat. Fortunately for all of us, galvanic corrosion is not a problem we often run into.

 

Great, I see we are on the same page. Glad to see when we can agree on something on these forums every now and then.

On a side note, here are some pics I took of my Ebay O2 housing and stock manifold that I had coated locally with the black thermal coating. It turned out really nice and is good for 1600 degrees.

Now, back to the "rust vs. corrosion" smack-down...

 

corrosion and oxidation are different but possibly related. corrosion can be a type of oxidation, some acids corrode and do so by causing oxides to form. this can be the same as oxidation, but isn't necessarily.

 

anyway, the smackdown is over.

as for coatings. remember don't coat anything after the turbo, use heat shields.

beware of coatings that have texture... you want smooth flow surfaces.

 

What? Why wouldn't coating the O2 housing be a smart thing to do? You can't use the heat shield with an eBay O2, and that is precisely why I want to coat it (or wrap it).

I really think I am going to go with a wrap on the downpipe back. It is good for 2,000 degrees and will also be coated with DEIs silicone spray to help lock out moisture and other harmful things. The full TBE is stainless and I think it would take a very long time for any real wear to show up on it. Plus, what would be more harmful, leaving it bear to the elements or wrapping and coating it? I also think I am going to wrap and coat the exhaust mani as it is the stocker and I will upgrade eventually. I don't see the point in paying all that money to thermal coat it when it can just as easily be wrapped; plus it will still retain the stock heat shield to help out.

As for the O2 housing and possibly the turbo hotside, I would like to get them coated and I am doing research right now to find a local (within a reasonable radius of Atlanta) shop that can do thermal coating.
