This was another easy chapter. The exhaust header is made of stainless steel. The engine compartment is fairly confined and RotorWay uses several techniques to manage heat. One heat management method is to wrap the exhaust headers with a high temperature cloth material. It feels like some sort of asbestos material. After the wrap is applied, it is secured with stainless steel straps and sprayed with a high temperature paint.

Out on the back porch the exhaust wrap is soaked in water prior to application. The wrap is applied in a spiral, two layers thick. It makes a bit of a mess. But, I was able to hose it off the patio easy enough. The wrap is secured with stainless steel hose clamps.

After the wrap is dry ( it took more than 24 hrs) it is sprayed with a high temperature paint. The kit came with black. I went to the automotive store and purchased the paint in white. I figure white will show stains better in case an oil leak or exhaust leak develops.

The paint specified it needed to be cured at 600 degrees for one hour. The label suggested to cure the paint by mounting the headers and running the engine. Well the engine is not ready to be run so, I found a machine shop with an oven that could bake the header as specified. The oven usually runs at higher temperatures and is used to strip paint off metal parts. The shop foreman was fascinated by what I'm doing and let me use their oven without charge.
