I primed the exhaust manifold last night with the Rustoleum 2000 F paint and let it dry overnight.
On the way in today, I began to think, "How many coats of primer/paint/clear are too many?
Too many coats of primer/paint/clear would prevent heat dissipation, wouldn't it?
Since I do not want the manifold to run too hot and warp, please let me know your experiences of painting this manifold for a running car.
FWIW I run mine bare naked. I agree you want as much heat dissipated as possible so as to avoid the ever prominent warping of these things. Why risk helping it along. No one sees 'em anyway!
I bead blasted the ones I had on my T and A I then used a cotton glove and Aluminum anti-size you need to rub it in really good lay it in the sun, wipe off the excess with a rag install it and drive the car 4-5 miles it will look like it has been ceramic coated. Both of mine looked great and never turned, color plus after the 5 mile drive it will not wipe off.
I would think that you do not want to dissipate heat at the manifold, you want to simply convey the heat to the tail pipe.
Just put it on and run it. The paint is going to come off eventually!
Good idea Steve. I'm going to try that.
I have been having mine powder coated with great results. No discoloration what so ever.Just my experience.
eastwood has a good manifold paint which I used on my 413 after many miles still looks great..one coat and done
has anyone tried stove black? Heck I don't even know if you can still buy it. It is used to keep your old cast iron stoves looking good. It came in a small can, you would shake it up & brush it on bare metal. after it dried you would polish it up with a soft rag. came out nice & shiney. Used to use it on air cooled cylinders. The guy that turned me onto it said they used to use it on airplane cylinders & heads. it would last for years & looked good.
I appreciate everyone's thoughts.
Having started by priming, I decided to finish with clear over flat black.
I'm currently looking for an industrial oven to cure the paint.
