Has anybody tried using VHT Flameproof, ceramic coating ? It's rated up to 2000F intermittent.

I've been running my engine with exhaust wraps and am very pleased with the reduction of under cowl temps but am aware of the concerns regarding longevity of the exhaust.

As I'm very near to returning to the airport I want to address this and go with a ceramic coating.

I have the ability and facilities to apply a proper ceramic coat, but it is difficult to source the material at a reasonable cost and timeframe.

  I can ship it away and have it done for about the same price and less time. But I can also purchase VHT locally. While it comes in an aerosol can, it is not paint. It can be applied as simple as you would a paint, but for best results, proper cleaning, bead blasting and oven cure are required, not unlike the usual ceramic coats.

  I always preferr to do things myself, but if anybody can say that this stuff is not up to the hype, then I'll consider shipping out the exhaust to have it done.

  I have about a week of work to do where I want the exhaust in place, but then I'll be away for a week, during which time I can send it out.

   Further to this, has anybody ever had their exhaust ceramic coated and then also wrapped it to provide even more heat reduction?
