With the rib lacing complete, the wing is now ready for the first coat of Polybrush. This fist coat is applied with a brush to allow it to soak through the wing sealing the fabric and providing a base for the remaining coatings. I started by cleaning the surface of the fabric with MEK. Then I mixed up some thinned Polybrush. Mixed at 3 parts Polybrush to one part reducer. Then I liberally brushed it onto the fabric.
