to soften the old seal. When the seal has softened,
remove the glass from the channel.
2 .
Thoroughly clean the inside of the glass channel with
sandpaper, removing all rust, etc.
3. Using new glass channel filler, cut the piece to be
installed two inches longer than necessary for the
channel. Place this piece of fille r (soapstoned side
of fille r away from glass) evenly over the edge of the
glass which will fit in the channel. The extra fille r
extending beyond the rear edge of the glass should be
pinched together to hold it in place during glass in­
stallation.
NOTE:
One side of this fille r (the outside of
the roll) is soapstoned. This is the side which
goes into the metal channel.
4. Brush the inside of the metal glass channel freely
with ordinary engine oil. This will enable the glass
and fille r to slide freely into the channel. Push the
glass with the fille r around it into the channel until it
is firm ly seated. After the glass is firm ly in place,
the oil softens the filler, causing it to swell, thereby
making a perfect, watertight seal. Trim off the ex­
cess fille r material around the channel and at the
ends of the channel.
NOTE: Glass should be installed so that rear
edge is parallel to the division post. Allow full
cure before water testing.
