University of Technology Sydney. Faculty of Science. This research explores three separate routes to assist with the interpretation of the evidential value of vehicle and architectural paint. This has been achieved firstly, by a survey was conducted on the most common colour of vehicles that were seen on the roads and a motorway within Western Sydney and another survey was carried out in five different carparks, also around Western Sydney, this second survey looked at the most common colours that were found on the stationary objects, such as on the pillars and wall.. The next part of the research focused on the effects of weathering on the clear coat and other paint layers to not only identify but also help differentiate it from other paint sources. This was carried out with already weathered paint samples and by preparing and weathering both vehicle an architectural paint samples in the Sydney, Australian climate. This study demonstrated that it is possible to not only differentiate between two paint sources that have be exposed to the natural climate, but even between different panels on the same vehicle. The final part of the research was then focused onto the weathering of architectural paint which was conducted on eight different paint samples from either oil or water-based formulations. These samples were exposed to the natural weathering climate in Sydney, Australia for up to 3 years. The findings from this research study have provided supporting information that will assist in improving the evaluation of the evidential value of paint. |
