REPAIR INSTRUCTIONS USING FIBER GLASS MATERIAL
6.
Using a grinder, cut down the welds or rivet
heads flush with the exterior surface of the repair
area.
7.
To complete the repair, use the procedure for
Surface Filling and Finishing (page 16).
DENTS
1.
Perform the steps listed under Preparation
Procedure (page 5).
2.
Clean metal to the bare surface.
3.
Drill or punch 1/2 inch holes in the dent to assure
a good anchor for the filler (Figure 52).
Figure 52. - Repairing Dents
4.
If the dent is over 1 inch, cover dent with a piece
of fiber glass cloth and saturate it with resin
mixture. Allow the resin to cure.
5.
To complete the repair, use the procedure for
Surface Filling and Finishing (page 16).
SURFACE FILLING AND FINISHING
After repairing the damaged area, apply filler and finish
the surface using this procedure:
1.
Following the manufacturer’s instructions, mix
enough body filler to re-establish the surface.
CAUTION-MIX
FILLER
ON
FORMICA,
TEFLON OR OTHER HARD SURFACE. DO
NOT WORK ON A POROUS SURFACE SUCH
AS CARDBOARD.
2.
Work the filler into the repaired surface with a
squeegee, making sure to fill all voids and
remove large air bubbles (Figure 53).
NOTE - Allow filler to extend above the
original surface to allow for shrinkage.
Figure 53. - Applying Body Filler
3.
When the filler is firm to the touch, plane and/or
file off the excess, still leaving the filler level
slightly above that of the original surface (Figure
54).
Figure 54. - Filling Repaired Surface
4.
Now, pre-shrink the filler, using a heat gun or
heat lamp. A minimum temperature of 49°C
(120F) is required for shrinkage (Figure 55).
WARNING-KEEP HEAT SOURCE AT LEAST
12 INCHES AWAY FROM THE REPAIR AREA.
