Guys,

I agree that the complaints have been the residual exhaust that gets on the plane, your hands and clothes. DDD suggested the candle scent, I have tried that but it seems the scent oils burn off and the kero residual still has a smell. I have also tried adding cologne to the clean up fluid, this helped with the airplane but doesn't help with the exhaust smell that got on clothes of the helper or yours. I understand that biodiesel doesn't have the petrolum aromatic aroma and smells closer to castor oil. If we could keep the torque advantages of diesel with out the petrolum aroma it might spark some additional interest.

Best, Dennis
