Step #2 Apply Poly Spray for first Sandable layer! Poly Spray Quart "Blended" already has the correct amount of reducer for spraying
Poly Spray is the second step of the Poly Fiber process. Poly Spray is the first "sandable" layer. It has talc for sanding and aluminum pigment for UV blocking. The aluminum prevents the light from shining through your airframe and looking like a bag of bones.
Applied just before the final color paint, this silver coating protects the fabric against ultra violet (UV) rays.
Poly-Spray is a high-solids, one-part aluminumpigmented, air-drying coating used to protect the fabric from ultraviolet damage and as a sanding base to develop a smooth finish. Reduce 4 to 1 with Poly-Fiber Reducer. Refer to this manual for detailed application instructions.
