ABSTRACT:
A method for removing coating defects from a vehicle body or the like includes the steps of putting a defect information mark on a defect portion of an inspected object's coating, recognizing a position and a removal setting of the defect portion from the defect information mark, and non-contact removal of the defect portion in accordance with the position and the removal setting recognized in the recognizing step. According to the present invention, only the defects are removed, even when they are very small. The non-contact removal step may include spraying a water jet to permit removal of a defect without damaging a base coat. The non-contact removal step is very straightforward. Therefore, the removal position need not be defined in three dimensions. Accordingly, the shape of the vehicle body or the like is not required to be input.
