These spots are the result of moisture trapped between the PPF and the paint. |
| 10235526 | In certain areas, a vehicles underbody may exhibit corrosion due to road-salt usage. As a preventative measure, a cavity wax coating is applied to the internal surfaces of underbody components and an undercoating spray is applied to exterior surfaces of specified underbody components. The service campaign describes the procedure to perform this preventative service on certain 2009-2014MY Genesis Sedan (BH), 2011-2016MY Equus (VI), and 2010-2016MY Genesis Coupe (BK) vehicles. |
| 10235525 | In some areas, a vehicles underbody may exhibit corrosion due to road salt usage.
