NOTE
Hardened adhesive will not remove easily. A
new blade works best to remove all adhesive
residue using care not to damage the fiber
structure.
2. Place the new window glass in the opening
and center it to leave an even gap top and
bottom, and from side to side.
NOTE
Use small shims to raise the glass in proper
position. Shims can be cut from the tremshield
tape (Figure 38).

3. Hold the window glass centered and have an
assistant mark the inside contour of the
opening on the glass with a china pencil.
Remove glass and place it on a table with
the pencil mark facing up.
4. Place masking tape on the inside surface of
the glass to just cover the china pencil mark,
leaving the outer surface exposed for the
adhesive. This will make cleanup much
easier. For ease of removal, do not overlap
the tape at corners.
