Hi,

 

I wanted to paint my manifold and my exhaust. I've got some 800 degree C paint, would that do it?

You can spend as much on engine paint and high-temperature paint as you would like.  

 

In my experience, high-temperature exhaust paint has very little binder in it so it looks great until the hot pipes are splashed with water and/or the engine is washed.  Then the coating flakes off and you are back to where you started. 

 

Your 800 oC paint may be formulated differently and be better.  It certainly has a high enough heat rating.  However, if you don't mind black, paint for refinishing barbeque grills/cookers works very well and has sufficient binder to stay in place.

 

In answer to your question about exhaust temperature, there is no single answer.  That depends highly on the mixture and tuning of the engine as well as how hard the engine is being pushed.  It is not unheard of for lean mixtures to get exhaust headers glowing cherry red.

That should be fine.

This paint I'm using is for BBQs. It's silver if you are interested.

Hopefully that paint has more binder than the stuff you buy specifically for manifolds.  Let us know how it works for you.  I am interested in hearing your results.

I've use the VHT Brand of paints for the manifolds, I've found them rather good.

But like anything, preparation is everything.

 

They also used to have Ceramicoat Kits, basically a Ceramic Paint, I've used it on alloy head combustion chambers and piston crowns with really good results, but they seemed to have dropped these kits from their range now. These were also really good on exhaust systems, just a bit pricey though for something like that.

It's hot enough to give your finger a bloody good burn. Ask me how I know !

My 998 with retarded ignition got cherry red in a few minutes idling :')
