Correction of uneven surface
.
Basically, the same as the steel panel. However, give a consid-
eration to the aluminum alloy characteristics.
1. Repair of sheet metal
(1) Heat with a burner.
CAUTION
•
Heat-up the panel until you feel heat with a keplar work
glove on the reverse side of the panel.
•
Keep moving the burner evenly to prevent heat from
concentrating in one point.
(2) Because hammering may stretch the panel, use a mallet
or plastic hammer.
CAUTION
Minimize the stretch and hardening, and give no hammer
dent.
2. Distortion check: Grind the surface with #80 to #120-grit
sandpaper and then check for distortion.
