38.
Use an iron to shrink out any wrinkles or puckers in the surface tape and
patches.
IMPORTANT: Do not apply heat to the full width of the tape as
tape distortion will occur.
Heat the edges or the center allowing one to cool
before heating the other. Use the iron to smooth and bond all pinked
edges on the tape and patches.
39.
Coat all surface tape and patches with thinned U-500 adhesive,
concentrating on dry spots and flowing the glue into the pinked edges.
IMPORTANT: Do NOT apply glue beyond the pinked edges. The edge of
the glue will be seen after painting.
