HPC coatings?

[tydon]

has anyone had any of there exhaust parts coated with HPC? looking at getting downpipe done

[Guest]

Funky had a turbine housing and headers done iirc. Wee wait by memory.

I had some headers done in the polished finished look. Kept heat down to a certain degree, but I think heat wrap or a combination of both would have been better.

I had some B16a honda ones done, really nice looking. Two years on rust was making appearance from the mild steel headers below/within. I would go high temp blue paint again like I did on my GTO extractors. When heat baked, it looks and lasts better than HPC. My 2c's worth of experience.

Vht or other?

[micbryce]

Yup VHC. Kind of gave it a non gloss powered finish. Just don't let your brain dead mechanic stick his bloody oily covered hands on them when he say "theses extractors look real good" oily paw prints make permanent makes

[Guest]

Were they stainless and did you prime?

[micbryce]

All mild steel. VHT was primed then coloured blue. Looked great, was 17 years ago. I'm not sure where the photos have gone.

doh my bad lol yeah i was talking to a work mate who had a mechanic spray his exhaust with it and it flaked off in a couple weeks?

[micbryce]

Needs to be done correctly to get best results. Had my GTO for 7yrs no rusting or flaking. The blue did dull off a bit but still looked good.
