Skimmed through the thread. Recently had a car in here with a Swain Coated manifold like "G" has. I was impressed by the fact that the guy drove the car to our shop a good 20 miles and when it got here, we were able to write up the paper work in 5 minutes and get to work. The manifold was hot (obviously) but not cook your hand like instant noodles hot the moment you touched it. You could rest your hand there for 5~10 seconds before it got unbearable. Granted some have a higher tolerance for pain, and some have a lower. But I'd say with just the coating alone, temps were definitely lower than uncoated with a heat shield.
Now depending on your manifold, I'd rock the coating AND use a heat shield.

I guess people read between the lines too much. Please read only what I type not what you think i'm inferring. If I wanted personable & to make friends i'd go to facebook or myspace. 

j/k I talked to several companys a while back when I was looking to get my setup coated and what I found is that the stuff that's rated to 2400* or what not is actually less effective if your application will not be pushing heat up around or close to that heat range. You actually get better heat controlling properties from a lower grade coating that is more around your range because the chemical make up of the coating is made for that kind of heat. I actually coated my HX52 setup and JHR manifold in VHT 2000* spray on ceramic coating and then cooked it on as per the can. To test how it would hold up I turned on the overn cranked it full blast and left it on for like 30 min and pulled it out and it was perfectly fine no discoloration or bubbling.
