Both the spar and the wing root area needs heat protection. Just engine heat and of course protection to give a few more seconds in the case of an engine fire emergency.

I’ve gone with a new technology ceramic heat shield, Zircoflex II. I had very good support from the Australian Distributor. The product comes with a quality 3M adhesive backing and just needed cutting with scissors to fit.

Cutting to fit meant I needed a set of templates to maximise  the material with a minimum of waste,

It took quite a long time to generate an exact set of thin cardboard that fitted my rather odd shapes.

Once I had the sets cut out it was easy to use the Zircoflex sheets with a minimum of waste.

Fitting was just removing the backing paper to reveal a very sticky rear end.

I spent quite a while with a wooden roller and then a wooden ice cream stick. This works a treat for getting the foil to really sit down in the corners and on the flats and intersections.

Its a good clean result.
