PGC has been applied to the characterization of a number of different types of polymers besides the traditional paint chips and fiber evidence submitted to the crime laboratory. Synthetic plastics have been readily identified and differentiated by PGC (253). Hume et al. (265) applied PGC to the characterization of motor vehicle body fillers utilizing a 15-m Carbowax 20 M gas chromatographic column and a computer-based system to compare pyrograms. 

Kevlar remanents can be stuffed into odd shaped body recesses such as window/ windshield pillars, front/rear quarter panels and under the dashboard. These pieces should be packed into the space as tightly as possible and held securely in pi ace.Care should be taken to insure that the armor filler doesn t interfere with any mechanical functions of the vehicle. 

Other applications are automotive body seals, mounts, weather-stripping, roofing, hose, tubing, ducts, and tires. Molded EPDM rubber is used for bumpers and fillers to dampen vibrations around the vehicle. EPDM can be bonded to steels, aluminum, and brass, with modified polyacrylic acid and polyvinylamine water-soluble coupling agents.
