FOREWORD

1 PURPOSE.

The purpose of this technical order is to prescribe standard procedures for the removal, application, and maintenance of coating systems on Air Force systems and equipment. Its applicability is generally imposed by reference in system or item technical data. It also should be used where there is an absence of paint process requirements in system or item technical data. System and item (SM/IM) management ac-tivities have an obligation to require the use of this technical order to the maximum practical extent. It reflects the use of standard materials and procedures that meet Defense Stan-dardization Program, AF Corrosion Prevention and Control Program, and Air Force policy (AFI 21-105) requirements.

SM/IM offices should modify standard requirements or specify alternate requirements only as needed to support the specific requirements of their systems and equipment as stated in TO 00-5-1. Where there is a conflict between this general TO and the weapon system specific TO, the weapon system specific TO will take precedence. Such departures from standard should also be coordinated with all applicable Office of Coordinating Responsibilities (OCR) (e.g., Corro-sion Control, Ground Safety, Bioenvironmental Engineering, Environmental Management).

2 SCOPE.

This technical manual specifies procedures, materials, and equipment for preparing surfaces and correctly applying ef-fective finishes to interiors and exteriors of Air Force air-craft, missiles, and associated equipment. Painting techniques are suggested and common difficulties discussed. Procedures for applying complete coating systems are given. Some basic discussion of paint technology is included and a glossary of painting terms appended.
