Inexpensive tool for detecting auto fraud

This inexpensive (~$15) paint thickness tester is a great way to help detect cars that may have been in accidents, no matter how squeaky-clean their title is. The paint thickness tester takes a reference value anywhere on the vehicle, and then tests other locations for uniformity. Uneven paint is a good indication that the car has been in an accident and reconstructed.
