Abstract

Defective coated workpieces are repaired. To this end a coated plate is placed on to the defective area so as to cover and overlap the defective area. A seal is disposed between the defective area and the plate and the latter is secured by means of bolts or screws extending through the workpiece from the uncoated side and extending into the plate.
