Overview: Hangar 9 UltraCote is a high tech polyester covering that features a unique multi temperature-controlled adhesive and shrinkage system, making it versatile and easy to apply. A patented polymerizing process permanently fuses the color to the polyester film covering, eliminating the possibilities of color-layer separation and permits repositioning the covering on your model. UltraCotes unique ability to both shrink and stretch make it superior to other coverings for going around tight curves and wingtips. Temp ranges are as follows:: Adhesion to wood begins at 200 to 220 degrees F. Shrinkage onset begins at 300 degrees F. Maximum shrinkage is at 350 degrees F. Detailed Information: Surface Preparation: The covering job can only be as good as the finish of the surface its applied over. In order for the covering to properly adhere to a surface, the surface must first be smooth and clean. Sand the model using a sanding block and progressively finer sandpaper, with the final sanding being done with 320 grit paper. Vacuum away all of the dust, as specks of dust under the covering will leave unsightly bumps. Fill gaps and dents with a high-quality filler. If using light-colored UltraCote (such as white or yellow), use a tan-colored filler that matches the wood color to prevent the filler from showing through
