REPAIR INSTRUCTIONS USING FIBER GLASS MATERIAL
4.
When working with fiber glass, always work In a well
ventilated area. DO NOT SMOKE OR EXPOSE
FLAME WHERE KITS ARE BEING USED OR
STORED. If possible, obtain a kit of material large
enough to accommodate only one or two Jobs to
avoid storing any quantity of the material. Resin
liquid must be kept In a metal container or cabinet
when not being used.
5.
Repairs must be ground or sanded to match
surrounding contours. When grinding or sanding, It
Is advisable to use an approved type respirator during
the operation. Suitable respirators are available
under equipment number SE-1 798 and SE-1799.
The ground dust or particles of resin or fiber glass
must not be Inhaled, or irritation may occur.
MATERIALS REQUIRED
Fiber Glass Mat (Figure 2)
This blanket of randomly arranged fibers is the repair material
you will use in all repairs requiring a backing patch. Its weight
is measured in ounces per square foot. For most of your
repairs, a 1-1/2 oz. mat is required.

Fiber Glass Cloth (Figure 3)
This material is made from continuous filament glass fibers
that are commercially woven on regular textile machinery.
Fiber glass cloth is used where the most strength and the least
thickness is needed. Its weight is measured in ounces per
square yard. A 10 oz. cloth is recommended for most
automotive repairs.

Resin (Figure 4)
Resin is a liquid plastic that hardens when combined with
another substance known as a catalyst or hardener. The resin
used for most automotive fiber glass repairs is polyester resin.
Because it is inexpensive and has a short hardening (curing)
time, it is used for repairs requiring the pre-forming of a
backing patch and is available from:
