Diesters of 1,4-cyclohexane dicarboxylate are surprisingly more efficient PVC plasticizers and fuse PVC faster and at a lower temperature than similar phthalates or terephthalate diesters. The wing members are releasably coupled to the decoy using a flexible mounting assembly that allows the wings to move independently with, and in response to, the wind. The pentacene precursor may also include an acid-sensitive protecting group, which in the presence of a photoacid generator and upon exposure to UV light, is removed and the product becomes base soluble. Preferable the switches are pre-assembled on supporting plate before it is mounted on the supporting body. To flush the cooling system of the engine, the boater connects a conventional water hose to the forward end of the flexible tube extending from the Y connector, opens the valve, and turns on the water.
