REPAIR INSTRUCTIONS USING FIBER GLASS MATERIAL
Body Fillers (Figure 6)
Polyester body filler is used in most automotive repair shops
because it is easy to apply and shape to the contour of the
surrounding piece. Machining of the body filler surface can be
followed if necessary by an application of glazing putty to
eliminate porosity and provide a smooth surface for painting.
It is available from:
Acryl Green Spot Putty
Minnesota Mining & Mfg. Co.
St. Paul, Minnesota 55101
Ditzler Red Oxide Putty
PPG Industries, Inc., Ditzler Auto Finishes
Detroit, MI 48235

As a matter of economy and to maintain the curing properties
of the resin, store the resin in a sealed container within a cool,
dry enclosure. This precaution will reduce aging caused by
changing temperatures. Keep a record of each purchase of
resin. In this way, you can always use the oldest stock first.
NOTE - The shelf life of resin varies; therefore, they should be
tested before using and discarded if not up to specifications.

Scratches and Gouges
In general, a scratch or gouge is minor damage that
penetrates the paint but only slightly into the laminate (Figure
7).
Figure 7. - Scratches and Gouges
Perform the steps listed under Preparation Procedures, and
then proceed with the repair as follows:
1.
Use a burr bit on a power drill to form a V-groove for
the length of the scratch or gouge (Figure 8). The
sides of the V should be tapered no more than 45
degrees.
