just wondering if spraying a greddy turbo manifold with engine enamel would be bad. i hate it how it goes rusty/brown/poo after like 2 weeks. so yeah, just concerned about heat issues if i sprayed it with engine enamel.

It'll burn.
If you want it black or silver use a ceramic coating like HPC etc
as said, u will need it HPC otherwise it wont loast
no engine enamel will work, i sprayed my turbo header with it also.
The other option is caliper paint which can also take very high temps
i might give caliper paint a whirl until i can afford to get it coated (Y)
umm isnt flame proof engine enamel rated at higher temps than caliper paint?
there flame proof vht paint rated to 1500F compared to 900F for caliper paint?
can't rem but i flamed them both for testing ;p
^lol that would be something i'd do.. ahhh the good old days experimenting in science and chemistry/phisics classes lol
lol i went to a crappy HS where the teacher had to do all the experiments cos we didn't have enough facilities. It was sad, he broke more equipment than all of us combined
lmao, hahaha
our physics teacher would go nuts, eyes popping out of his head, going red and he was scrawney too so funny,
nothing beats our chem teacher, had a hot air balloon experiment where tissue paper balloons were made, whilst heating the air with metho in a cup to simulate the firing in a real balloon, it rose to head height and just some how blew up in a fire ball, singe his eyebrows off, all red in the face, everyone even him, were pissing themselves laughing hahaha.
back OT!
Whether or not these 'paints' will last all depends on under-hood ventilation/temps.... But most will burn off.. if not in days, in weeks or months.
mine's been on for over 6mths. Also i've even gone to Canberra and back with it, no issues still

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 :)
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....Quote:

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
