APPENDIX I GLOSSARY

EPOXY FILLERS
Epoxy fillers (body fillers) are simple to use in that the body portions do not have to be straightened as closely as when making repairs without it. By using the manufacturer's instructions, you can apply body filler over rough places and form it with a body file or sanding until it conforms to the desired contour.

The advantage of using body filler lies in the fact that a badly damaged vehicle can be returned to a like-new appearance quickly and with a limited amount of metal straightening. Additional, the use of thinner metals in the bodies of modern vehicles makes it difficult to reform panels into their original shape.

Should you have an opportunity to use an epoxy filler. the recommended thickness of the filler should be kept to approximately 1/ 8 inch. If more is required. it should be applied in coats and allowed to dry before applying the next coat. Do not exceed an overall thickness of 1/ 4 inch.

IDENTIFICATION MARKINGS
Once a vehicle has been repainted, you will be required to replace the vehicle identification markings. The placement of registration numbers and other equipment markings for identification purposes, as required by law, are described in the NAVFAC P-300 and COMSECOND/ COMTHIRDNCBINST 11200.1.

CORROSION CONTROL
Civil Engineer Support Equipment (CESE) is assigned to many locations where atmospheric and environmental conditions can cause severe corrosion

and a reduction in equipment life. Corrosion can be slowed by proper cleaning and the correct application and maintenance of protective coatings, such as paint, occurs primarily where poor ventilation caused by clogged drain holes or accumulations of mud and sand allow moisture to remain on unprotected metal undercoating, and preservatives. Body corrosion surfaces.

All automotive CESE will be core-treated. Proper application and preparation of the areas to be coated or recoated is necessary. Surfaces shall be reasonably clean, dry. and free of excessive rust, oil, grease, dust, road tar, and other foreign matter. Core treatment of a vehicle will be inspected during each preventive maintenance (PM) service: one scratch through the preservative can cause corrosion to start beneath the rustproofing.

The NAVFAC P-300 identifies and describes the different preservative compounds applicable on CESE. Additional information can be obtained from the NAVFAC P-434, Construction Equipment Department Management and Operations Manual.
