    From memory, Paul Smith did. I think it would have been through European Autocare.

    I had the 4CVG's stainless extractor ceramic coated. Radiant heat is noticeably reduced. I can think of no downside except cost. Mine was done by a Victorian mob called Jet-Hot & the coating was a metallic silver called Sterling. No complaints. Lots of folk will do it though and lots of coating variations.

    cheers! Peter

    Yes, that's my recollection too. I think he only coated the outside, some mobs like to do in and out.

    That said, I imagine a lot of Dee engine bay heat is general accumulated warmth, rather than the specific radiance of a hard-working exhaust manifold.

    p.s. Can we have the big discussion on ailes cendriers again, now, too?

    That and the fact it is in front of the driver's legs.

    Well, he should have ceramic-coated his legs!

    All D drivers need ceramic coated legs. . .

    I find these images interesting from the point of view that the heat shield on the exhaust has more than halved the heat off the manifold - this is D running at operating temp.



    I'd be hesitant to play, but if there were further insulation on the manifold heat shield keeping the heat from being dissipated throughout the engine bay and restricted to the exhaust - with perhaps better insulation at the muffler shield under the driver, less heat would be transmitted into the cabin space?

    Cheers

    D manifold shields had a slice of asbestos on the underside of them originally did they not? Pretty sure they did.

    I dunno, where am I.

    So adding something on the underside with moderne material could be of benefit to the starter aussi.

    I ceramic coated the exhaust inside and out on my D, it did seem to help, haven't put a temperature gun on it to check, but hopefully later in the year when I bring it to Perth to set up the carby with a dyno

    Me too - though I did it mainly for aesthetics. Painting them never seems to last...
    If your going to do it include the drop pipe between the manifolds and the flex. I'm guessing most of the heat soak into the footwell comes from this pipe.

    I don't think so Steven, I can't recall late Ds ever having insulation on the manifold shield. Mine certainly didn't and neither did the repro replacements. I can't recall but perhaps the early cars?

    Would be interesting to get some temp readings on your car of the same areas as the pics above Mark. Not sure if my infrared temp gun reads to 300+C

    Edit: Just checked, yes reads to 550c

    If you mean Paul Smith, didn't they crack within a couple of years too. I seem to recall he wasn't displeased with them... they were just massively expensive for a barely detectable change.

    It's a shame we hadn't found that insulation back then. Even his ignition used to get red hot from memory.

    I am also intending to do the ceramic treatment on in and out manifolds and the cam covers. Not for heat management but so they will retain their 'new' look for years. The only thing I'm thinking about is whether I polish up the cover and get a transparent ceramic coating or use a silver-ish colour. Any heat management benefit is a bonus.

    Some did. Some did not. I think I have a 72 here today that does.

    I have done 3 D's now. Both manifolds and the engine pipes inside and outside. I agree, there is no noticeable difference in performance. But. Even if you don't buy into the heat, performance and longevity improvements quoted by the people that offer the service. Rusty manifolds and downpipes are no fun to work with, like fingernails down a black board.

    HPC (High Performance Coatings ) in Leongatha, offer a good service, they have a courier pick up and delivery, I did one recently, was $400 from memory.

    IIRC The ceramic treatment in the engine bay pushed all the heat to the Y joining section and flexi pipe then the silencer. It resulted in cooking these parts prematurely. Heat soak still through the floor and silencer. The aluminum radiator likewise suffered from massive heat sink (quick extremes) over that of the original spec unit. Excellent attempts at removing heat from the bay but never as successful as it appeared on paper.

    Ye, Chris is correct, they're brake discs, black because they were NOS, and I went over them with rust converter, before I cleaned them and fitted.

    There is multiple areas to address in an attempt to arrest heat soak. I'm sure we've all seen many of them here already, my take on it is to tackle as many things as reasonable at the time in the hope that the accumulated effect of multiple solutions offers some meaningful difference.

    one of the beaches here is littered with asbestos that was dumped post Tracy and the levelling of the old hospital, I take the dog for a walk there, if I collected enough pieces I could make up a mosaic of asbestos for the heat shield!!!!

    Believe it or not....

    Both my Aussie IDs 1962 and 1965 models have asbestos fabric riveted onto the underside of the exhaust heat shields. Quite scary, and my wife reminds me regularly of its presence. Will eventually remove it (drench with water first, wear a mask) and replace it with modern stuff which is readily available locally.

    i was not sure if this thread would get any replies, to my surprise however, appreciate all the information.

    my starter is stuffed and i realised that this would be the best time to deal with this, having known about CC for some years. this initial question was to satisfy my curiosity in the first instance as to the experiences out there.
    the car is getting a new starter and also manifolds being CC in black. not silver , also as i understand the latest process is that it is being baked not air cured. also i agree with MB that it is an accumulative effect.
    everything i do to this car, is to make is more user friendly while retaining the originality. the time has come that i am using this as my daily driver now, so reliability comfort etc is important.

    thanks for the great information and differing point of view.

    next on the list is driveshafts ??
