(6) (7) (8) (9) (10) (11) (12) (13) (14) (15) (16) Size the block insulation or cutout to fit the opening where the skin and foam were removed. If a cutout is used, remove the aluminum skin from one side of the cutout. Remove all paint or foreign matter from the overlap area on the skin of the shelter and an area approximately one inch around the scribed mark using emery cloth and cleaner. If the cutout is used, remove all paint or foreign matter from the aluminum skin of the cutout. Roughen the skin surface with coarse grit emery cloth. If a cutout is used, roughen the surface of the aluminum skin. Coat the interior of the opening where the skin and foam core were removed with mixed adhesive (paragraph 4-7.b.(4)). Insert the block insulation or cutout into the opening where the skin and foam core were removed (D, Figure 4-5). With the aluminum patch over the puncture area, drill #30 holes, around the perimeter of the patch, 1/2 inch from edge of patch and on one inch centers. Coat the exposed block insulation or cutout and the overlap area with mixed adhesive. Dip the pop rivets in the mixed adhesive and use the riveting tool for pop rivets to install the aluminum skin patch as shown (E, Figure 4-5). Smooth and taper mixed adhesive (squeezed out during the riveting process) along the edges of the aluminum skin patch and immediately remove excess mixed adhesive with cloth saturated in toluene solvent. Prime and paint the repaired surface. (Refer to paragraph 4-12.) Inspect the repaired area to ensure that rivets and paint were applied correctlv. . . . . . . 4-14
