Smoke on high temp paint

[voucht]

Thanks Mike,
Actually you are right, 650°C is not enough for an exhaust manifold, and it is more adapted to brakes. I couldn't find 1200°C, but I know where to get 800°C paint which seems to be the most popular one for exhaust parts.

However, I have read some forum here in Sweden about the paint I used, and it looks like this paint has to be «*cooked*» to be hardened after being applied. People put their parts in an oven, ore use a heat gun. Some other say that running the engine for exhaust parts and letting it cool down id the way to go, and will do the hardening job.

That is what I did yesterday. After 10-15 minutes of running the engine, the manifold stopped smoking, and the paint still look nice and hasn't been affected by the heat.

I'll have another run today from cold engine, and see what happen, but I think I am going to leave it like that if everything looks OK.

Thank you for the inputs.
