REPAIR INSTRUCTIONS USING FIBER GLASS MATERIAL
INSTRUCTIONS FOR HANDLING AND DISPOSING
OF THIS MATERIAL.
Use an applicator or make a craft paper cone
dispenser to spread adhesive on or between the panels
(Figure 45). Make sure the bond area is completely covered.
Figure 45. - Applying Adhesive
Press panels together and use clamps or weights to
hold panels in place (Figure 46).
Figure 46. - Holding Panels In Place
Use a rag and acetone to remove any excess
adhesive squeezed out. After adhesive has cured, it
will be difficult to remove except by grinding or
Allow sufficient time for adhesive to cure before removing
clamps or weights. Heat lamp or gun will speed up curing
WARNING - KEEP HEAT SOURCE AT LEAST 12 INCHES
AWAY FROM THE REPAIR AREA.
REPAIR PROCEDURES - SHEET METAL/ALUMINUM BODY
Repairs to sheet metal and aluminum body components can
be made using fiber glass mat, cloth resin and/or the polyester
body filler and glazing putty. Torn holes, rust holes or
damaged surfaces which are difficult to refinish with the usual
sheet metal or aluminum repair procedures can be repaired
using the materials listed above.
A combination fiber glass mat and cloth patch can be used to
repair holes in metal. However, a metal patch, where
practical, provides a more permanent repair. Procedures are
given for both types of repair patches and also for dents.
Repair Using Fiber Glass Cloth and Mat Patch
The following procedure can be used to repair both small
holes (under 3 inch diameter) and large holes (over 3 inch
Perform the steps listed under Preparation Procedure
Clean metal to bare surface with 16 or 24 grit
sandpaper approximately 6 inches beyond area being
Dent in area being repaired about 2 inches beyond
Cut a piece of fiber glass mat about 1 inch larger than
the surface being repaired, then a piece of fiber glass
cloth (two or three pieces of mat may be used to fill
the indented area).
Brush the resin mixture on the damaged area and
then saturate the layers of mat and cloth being used.
Allow the resin mixture to get tacky.
NOTE - When repairing large holes, prepare the patch as
On a piece of polyethylene film, position a piece of cloth larger
than the hole being repaired. Saturate the cloth with resin
mixture. Apply two layers of mat (Figure 47) saturating both
with the resin mixture.
