12. Body Sheet Metal and Paint Repair Manual 12-3 BIW assembly BIW assembl y 12.1 BIW assembly 12.1.1 Characteristics of plastic materials Considering that some parts may be deformed by heating during repair, the characteristics of the plastic parts (solvent resistance and heat resistance) shall be confirmed, the repair materials shall be selected with reference to materials of plastic parts, and only a small amount of alcohol shall be applied for degreasing within a short time so as to avoid damages to materials. If necessary, remove parts in advance.
