The Sam James cowl has a special porous fiberglass material on it that keeps the weight of it down to a minimum. However, this porousness also is a great trap for water and oil from the engine. Sam James recommends sealing the inside of the cowl to keep any contaminants out of it. The best way I thought to seal the cowl was to mix up some epoxy and microbaloons. I started out with a WAY too thick mixture. My theory for making it thick was to keep it from dripping and pooling up from gravity. I applied the thick mixture on the right hand side of the pic. It was a total PITA to apply. I used an old credit card to spread it. For the left side I made the mixture a bit thinner. That was the ticket. It was easy to apply and didn't drip that much. I got a good first attempt finished tonight. It will need some more attention later on.
