This vehicle has overspray damage in the form of Protective & Marine Coatings. Several storage oil tanks at the owner's job site were being painted. There were a total of 125 vehicles damaged. The normal cleaning methods using the clay bar were useless in this case. These coatings product have a 20 year plus life span when applied to any surface. The technique that I am using is called blading. I started this method of removing overspray many years before the clay bar was invented. This method has never failed me in over 23 years and thousands of vehicle repairs. I am the only person on the net that has demonstration videos of removing these products.
