Scientists Examining Trace Evidence on Vehicles

What are scientists examining when looking at the base layer of paint on a vehicle?

A. Pigment

B. Clearcoat

C. Primer surfacer

D. Electrocoat primer

Answer:

C. Primer surfacer

Scientists examining trace evidence are focusing on the base layer of paint found on a vehicle, which is called primer surfacer. This layer is essential for providing a smooth surface for the paint to adhere to, making it an important aspect to analyze in forensic investigations.

Primer surfacer is the foundation for the paint job on a vehicle, helping to ensure the longevity and quality of the coating. By examining this layer, scientists can gather valuable information that may help in solving criminal cases or identifying specific vehicles involved in incidents.

Understanding the composition and properties of the base layer of paint can provide crucial evidence in forensic science, shedding light on the history and origin of the paint on a vehicle.
