ceramic coating and header wrap

[jmgtp]

just to let everyone know, i just got done coating Ben's exh. manifolds with "cast iron" ceramic. check out the pics:

whoa! those are nice.

here like a dozen questions :P :So will the heatshields be going back into place or does the ceramic paint work well enough that the heat shields arent necessary?Did you get the inside of the manifolds too?

How much did that paint cost? spray on? prep work (like sanding) or just clean with like break cleaner and spray right on the rust?

I really like the way they came out, if you dont mind sharing the name of the product used, cost, where you got it, and prep work that would be real cool.

I won't know the performance benefits until Ben gets them back and puts them on a car.

Ben got the stuff from columbiacoatings.com , same place I get all my powder for powder coating (http://www.60degreev6.com/GPXSS/pcoat) it was $38ish for 8oz, it took about 2 oz to do those 2 manifolds.

Prep consists of sand blasting (do not use glass bead) the parts inside/out , then spraying and wiping down with brake cleaner (ran out of B-12)

Stir up the stuff before you use it, it has solids which must be thinned. I sprayed it through a $25 auto 'touchup' gun with a small cup at 40psi. Spray 1 even coat on part, do not overspray or spray on multiple coats. Partial cure is at 500 some odd degrees for 30 minutes. I used 525 for about an hour to make sure, full cure is after parts are on engine and run.

omg, did lorenzo log in as chris...or did he eat a cake baked in that over...

I wont know any perf diff cause I just ported the heads more.

I ended up spraying only the outside of everything and the inside of everything i could reach. So far the verdict is that header wrap is better then just spraying the outside but it is definately cooler then uncoated. Before the radiating heat was enough to burn the hairs off you arm from 6" away, now it is still hot but not hair burning hot.

I'm going to have to fab up some heat sheilding still cause it is hot enough to melt wire loom . How well do you thing aluminum flashing will work?

No clue, but I have some here. I guess give it a shot and see what it does. I don't have a clue what kind of heat it can take either.

brian you are using ceramic coating and header wrap?

[brian89gp]

na, scrapped using header wrap. After taking the old stuff off and itching for a few days I said never again, too bad cause that stuff cut down on heat a whole hell of a lot.

Update:

After driving it some the coating has started to really work quite well, guess I didn't cure it for long enough before. It still doesn't knock the heat down as much as header wrap but it is a big difference from uncoated.

Cool. I wonder if doing the inside and outside would double the outcome?

That was too much to take in at once!! :P

I dunno if it helped more or not but chris did as much of the inside on my manifolds as possible. On headers it will help performance some, but manifolds...dunno. I bet it will help on a turbo quite a bit.

We need to find some of the cermaic meant for moving parts (that you can apply yourself).

Hehe, I actually didn't care if it even hurt performance. I was just tired of it melting all the wiring and hoses in the general vicinity.

Here is a pic of my front manifold with ceramic coating.
