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 Figure 6.  - Body Fillers 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.
