Dry with a clean, damp chamois, a soft, clean cloth, or a soft tissue by blotting the surface until dry. If the surface does become charged, patting or gently blotting with a damp, clean cloth will remove this charge as well as the dust. Apply the compound with a soft cloth, rub in a circular motion until clean, soft cloth. You may be required to remove and install and polish with another canopies, escape hatches, and other aircraft structures that contain plastic sections. The finish of the plastic must be protected.
Plastic is very soft as compared to other aircraft structural materials.
The surface is easily scratched or damaged, and should be protected by the use of proper protective covers and storage racks, which are provided by the aircraft manufacturer or manufactured locally. It is easier to avoid scratches than to remove them. It is possible, however, to restore even a badly scratched surface to a good finish by buffing and sometimes sanding. Aircraft MIMs and SRMs specify limits on the length, width, and depth of cracks, and in what areas they are allowed. These measurements are normally made by the use of an optical micrometer.
