I haven't used Eastwood paint, but they do have some neat stuff in their catalog - like the paint that makes the manifolds look like new cast iron. Have used a lot of other stuff from Eastwood and it is excellent quality. Personally I have had real good luck with VHT High Temp Exhaust Paint. As an earlier post explained, the secret to getting good results is in the preparation. If you don't have access to a bead blaster, clean the manifolds completely with a wire brush and maybe course sandpaper on real bad spots. Clean well with lacquer thinner and let dry throughly. Hang them on wire in a place you can get around them and put on several thin coats of paint. I have snuck them into the house and put them in the oven at about 200 degrees for a couple of hours to cure the paint (actually that might explain why I am now single, too). Good luck.

I sorta need to disagree with 4Jaw on this one. Powder coating is NORMALLY polyester polymer but it can be any kind of thermo-plastic material such as nylon, vinyl, polyethelene, anything that can be powdered and melted. He is right, it won't last on headers - way too hot. Headers need to be metallic-ceramic coated. Period! However, I have found powder coating works great on everything else including engine blocks, heads, intake manifolds (look at the closeup picture in the Photo Album section of this site of my hemi with a glossy orange powder coated intake manifold with stock exhaust x-over. No burns.), the entire exhaust system downstream of the headers (see the side view of my Willys in the Album - those flat black powder coated header mufflers are like new after about 20,000 miles), etc. Catalytic converters are likely a no-no but everything else is fine.

And I still have a couple of pastel, double breasted, bell bottom polyester suits. Too groovy to get rid of although I need to lose about 120# to wriggle into them again! Maybe if I lay the sky blue jacked over my exhaust headers and start the engine . . . . hmmmmm . . . .

Thumbs up

Sandblast your exahust manifolds and then coat them with POR 15 exahust manifold paint. This is good stuff.



High Temp. POR 15

I have been following this thread with a great deal of interest. I have a can of Plasti-kote Hot Paint, aluminum color. Throw it away, or can I make it work if I do all the prep right?

What kind of powder coat did you use on the intake and pipes Willy? I have never used anything but polyester powder.

I got that info about the various resins, from my powder coating guy. All I ever used is what he has in his gun at the time, as long as it's the right color, again on recommendation from my guy. He advised that the specialty resins had very narrow application and that the run of the mill polyester was as tough as it gets for 99.99% of all apps. I was really doubtful too when he told me that I could coat everything but the header itself but I am a big believer now. I have coated exhaust systems, engines, transmissions, and frames on three cars now and not only does the coating not burn off, it doesn't even lose its original sheen (gloss stays glossy, semi-gloss and flat, ditto). The only thing I paint on a car now is the body (catalyzed color/clear coat urethane only). Everything else is powder coated, chromed, or for headers ceramic/metallic coated. Sounds expensive and it is a little more at the beginning but my finishes are as near zero maintenance as you can get and still in show condition when needed. Since I tend to keep cars a while (eg., Willys for 40 years), it's a good investment. If I was building a car and selling it every couple of years, of course I would probably go a totally different route.

Madd, just finished doing this to the factory manifolds on my 400M. I almost forgot about this trick and it works excellent on cast iron or steel, it actually lasts longer on rusty cast iron...seems to soak into the rust and stay put. It is water based so there is no smell when you first start it up too.
