2、TOMOTIVE CAVITIES 1. SCOPE The material defined by this specification is solvent free based rust preventive compounds with minimum 99% solid content and contain an UV- marker. 2. APPLICATION This specification was originally released for cavity waxes sprayed into box sections below the floor panel (

3、rocker panel, side and cross members, etc.), in the engine compartment and to lower areas of pillars, doors, hood and tailgate. They are applied to the vehicle body after the paint process, prior to final assembly. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers
