I've used Duplicolor high heat paint in a number of applications, but never on any components that are exposed to extreme heat.

I'm going to be getting a old RB header soon, and what ever coating that used to be on it is gone. So my plan is to take my mini grinder with a sanding wheel on it, and getting rid of all the rust, and shooting a coat of high heat enamel on it. Will Duplicolor 1500 degree paint with ceramic hold up in this application?

I don't wanna pay for having the part dipped and plated.

Also what do you guys use for painting the aluminum rotor housings? Is there a high heat primer you shoot first, cause I know conventional high heat paint doesnt like to stick to aluminum and no ferrous metals in general. (found that out after painting my dirt bike's magnesium components.)

Considering the rotary exhaust is ~2000 degrees or there abouts, I think that paint won't last. You could get them ceramic coated that would work.

Paint it with LOTS of coats and check often to repaint.

That wont protect the steel from rust thou. If anything it would hold in moisture.

This POR stuff looks promising

yeah , the high heat paint will burn off within minutes of the car warming up. i allready tried . the smell was terrible ...

Dang.... I'll probably find the highest heat rated stuff I can and try it anyways.

How will wraps hold moisture in? You just said its 2000 degrees, don't you think it will evaporate at that temp?

jet-hot 2000 does the trick. it better, cost me $300 coated inside and out, roundtrip shipping.

but it sure do look perty and rust resistant.

If I dont protect my header with anything, and just wrap the bare steel with heat wrap, than when my car is sitting not being used, or driving in wet weather the wrap will absorb the moisture and hold it in.

Once the car is started and the header heats up, the moisture will dissipate, but while sitting it will hold in moisture.

I don't have 300 to spend on coating. I want a do it yourself product.

I used off the shelf exhaust flat black..
It didnt burn or flake off yet.. no primer or anything.

If anything the paint faded a little and it just looks grey now.. still much better than rust brown

Dupli Color

Did you cure it at 300 degrees in an oven for 2 hours like they say to do?

Or did you just spray it, and bolt it on?
