Applied heat shield insulation to the inside of the cowl to protect against the hot exhaust tubes.
The way this worked is that Wayne had an idea how he wanted to do his, so we tried it out on mine. I think it worked out great. We used a hot rod market high temp spray on contact cement to tack on some upgraded heat sheild material. This stuff has a fiberglass backing and a high temp metallic shiny surface. It will reflect heat and insulate, good to ~1200 degrees (the material that is).
We cut it to shape and decided we needed to build up the corner of the cowl bottom to air inlet duct with a thin strip of material. This allowed the second layer to lay down better.
Jesse B. helped out a bit, and it was good to have an extra set of hands when messing with the contact cement.
Then we fit the lower cowl on to the plane. The exterior is looking ready to fly!
