Poly tak is what you glue the fabric to the airframe with, I do not care for it and use Sigs Stix-it. The first step after covering is the Poly brush (the pink stuff), it is an overall adhesive (glues the fabric to the wood anywhere it touches) and weave filler. Next is the Poly spray, whish is the first and pretty much only sandable layer, it is packed with aluminum for UV protection and opacity. Third is the Poly tone which is the colors, in how ever many one chooses. And then last is the clear coat, of which I am using an automotive type safe over vinyl.
