![]() ![]() Older Methods of Automobile Paint Thickness Inspection As large numbers of low-mileage vehicles come off lease and are being cycled through commercial and government fleets, inspectors and buyers rely on recent developments in thickness measurement technology to help determine vehicle value. Improved collision repair quality has made it harder to spot value-decreasing damage. On some recently manufactured cars and trucks it is not uncommon to find all three materials-doors and fenders made of steel, roofs and hoods made of aluminum, and bumpers and mirrors made of plastic. While metal panels are easily dented by minor impacts, plastic body panels are more resistant to damage. Lightweight, they allow designers the freedom to create innovative concepts. Both these metals require painting for corrosion protection and cosmetic appeal.īumpers and fascia systems are commonly made of plastic and composite materials. Now aluminum is used for some components as manufacturers look for ways to reduce weight without sacrificing safety. Traditionally, steel was used exclusively to manufacture automobile exteriors because it balanced cost with strength and machinability. Modern automotive construction methods now include materials such as aluminum, fiberglass and plastic. ![]() Besides having limitations in accuracy and resolution, the largest drawback of many such magnetic instruments is their inability to determine paint thickness on anything other than steel. Unlike visual inspections, these instruments provide reliable and quantifiable measurement results.Īt first, efficient and affordable paint inspection methods were limited to using magnets or inaccurate magnetic pull-off testers. ![]() In recent years, buyers have begun to rely increasingly upon electronic paint thickness meters to accurately assess paintwork quality. ![]()
