u relise that not when ur engine gets really hot.

engine might not but the headers gets continous exhaust fumes heating it up

The difference in temperature between cruising on the highway and high RPM track work is VERY significant. At cruising rpm and throttle, the header look normal. At high RPM full throttle, your header will glow red. It is a big difference. And no regular blowtorch is going to be able to simulate the temperatures that the paint will experience.

well still there for more than 6mths with spirited driving :)

The other option is caliper paint which can also take very high temps

your right about enamel, i tried it all on a set of headers years ago... the only thing that works are those really high temp ones from bunnings that AREN'T shiny....

the one i got that worked and never peeled off was called Self Priming Pot Belly Black from bunnings... 800*C temp limit. it looked matte...

the stuff i ended up using was 800*C proof.

ohh I might give this a go

well, with turbo cars, its not uncommon to get the manifold glowing red.

That happens at around +800 'C so ur paint goes out the window


On that note, no wonder my caliper paint cracked. Ive gotten my brakes to glow red
