Abstract

The variety and complexity of primers and paints now used to refinish automobiles assist the forensic chemist in making more specific comparisons of paint samples. Infrared spectroscopy was used to determine the chemical composition of 254 samples of refinishing topcoat products and to establish a data base for comparisons of spectra of unknown samples. Spectra representative of six major types of refinishing products are presented.
