A major auto manufacturer with headquarters in Dearborn, Michigan, is committed to developing and implementing innovative and sustainable vehicles. They purchased an articulating video borescope for cavity wax inspections. Cavity wax protects the inside of vehicles and metal surfaces from rust and corrosion. It is important that the wax is spread evenly throughout the cavity but it is difficult to see the entire space without taking the whole piece apart. Remote visual inspection of cavity wax with borescopes, like the VJ-3 fully articulating video borescope, saves maintenance professionals time and money.
