IN SHEET-METAL WORK repairs, involving shapes with double curvature, the principles re-semble those in panel beating in regard to obtaining the desired contour-stretching, shrinking or compressing the metal, planishing and finishing.
In some instances, repairs may seem more difficult than straightforward hollowing or raising of a sheet, owing to constraint to a given shape, and to the metal often being rolled iron or steel which flows less easily than annealed brass or copper. The presence of paint may also be a complicating factor, as may the difficulty or imposstbility-owing to space limitations-of directing on to the damaged area just the type of blow required.
