TREATMENT AND PAINT SPEC FOR TACTICAL VEHICLES AND COMPONENTS

1. GENERAL

A. This drawing establishes the minimum painting requirements for chemical agent resistant coatings (CARC) for

vehicles and equipment that require camouflage properties in field use.

B. Unless otherwise specified, the finishing processes and materials shall be selected by the contractor as specified

on this drawing and will consist, of cleaning method, surface treatment or metal coating, primer and topcoat. The

contractor is responsible to assure that epoxy primers are compatible with polyurethane topcoat.

Compatibility/adhesion should be tested prior to use.

C. Surfaces not to be painted:

Painting may not be required on certain types of surfaces such as fabrics, plastics, rubber, glass and metal parts not

requiring corrosion protection or where paint interferes with function, and surfaces specifically intended for electrical

contact or heat transmission.. Unless otherwise specified, these surfaces should be masked or otherwise protected

during painting.
