BUILDING WAX POSITIVE
  Molten wax is applied to the inside of the urethane mold with
a natural bristle brush.
Many layers of wax are slowly built to assure uniform thickness
of approximately ¼ ".
 
  Back section is built to same
uniform thickness.
Wax is released from mold after
sufficient cure time to prevent
warpage.
 
  Front and back sections are joined
together with molten wax and joint
seams are " chased " to appear seamless.
