Beat with a hand hammer from other parts than from directly above the underlay iron. The
underlay iron is placed against the lowest part of the dent, and then the higher parts near the
dent are beaten with a hand hammer.
Generally, when trying to repair the dent with a hand hammer and an underlay iron, the convex
side is beaten with the hand hammer and the concave side is pressed against the underlay
iron. First do brief correction by beating the damaged part with a wooden hammer, and then do
finer repairing with an iron hammer. For a larger area of dent, the underlay iron should be
placed against the place where the dent is shallower, and the hand hammer should beat the
higher parts. Besides, the wooden hammer and the iron one should be used alternatively
according to the actual situation.
(2) Repair the dent with a shaping spoon or tommy bar. Shaping spoons and tommy bars are
commonly used tools for door panel maintenance, and they are customized according the
characteristics of the vehicle body. They can reach the limited space between door panels to push
up the dent. This method is suitable for the narrow room between the door panels where it is
inaccessible for the underlay iron or the hammer, and the shaping spoon can act as a underlay iron
to distribute the impact of the hammer over a larger area.
(3) Restore the dent with a dent smoother. The dent smoother is applied to the inner side of the metal
panel and it is used for the dents that are hardly accessible to other tools and it is usually operated
in the following two ways:
Slide hammer
Handle
Flat gasket

Puncturing: Drill a small hole in the dent with a hand power drill, and then insert a pull-rod with threaded
head or hook-shaped head into the hole. Slide the slide hammer on the metal pull-rod and impact the
handle repeatedly so as to pull up the dent gradually. Make more than one holes when necessary, and
fill the hole(s) by soldering and polish the spot(s) when the dent(s) is/are smoothed.
Electrode welding: Weld a peg or a flat gasket onto the dent with a special spot-welder, and then use a
dent smoother to pull at the peg or flat gasket till the dent is smoothed. More than one peg or flat
gaskets can be welded when necessary so that the whole dented area can be dragged out. Finally,
break the peg or flat gasket, and polish the welded scar with a sand mill. This method can avoid drilling
the metal panels and prevent potential erosion, so it is widely used.
4.2. Restoration of Stretched Parts
When the metal panel is impacted, the dented area would be stretched. At times even proper
operations can not restore it, the heating-contracting method is sometimes used to achieve the desired
