d.
Inject sprayfoam into puncture. Mound sprayfoam to about 1/8 in.
(3.2mm) above surface of unbroken skin. Apply bead of sealant about
1/4 in. (6.4 mm) wide over all cuts in skin leading out from puncture.
Do not smooth out sealant.
e.
Plan how puncture is to be covered with tape before applying any tape.
Length and width of tape, number of tape strips, overlapping, and how
tape is applied will affect sealing capability of repair. Each piece
of tape should extend about 1-1/2 in. (3.81 cm) beyond sealant it will
cover. If this will require more than one strip of tape, tape should
overlap about 1/2 in. (12.7 mm). If three or more strips of tape are
required, center strip should be applied first.
f. Holding tape taut, apply it perpendicular to panel skin. Do not apply
with rolling motion either end-to-end or center-to-ends. Do not rub
each strip in place individually. Apply all strips lightly with proper
overlap and rub into place.
If necessary, damaged tape can be replaced; however, it should be
g.
removed with careful peeling motion to avoid damage to sealant. If
sealant also peels back, new sealant should be applied. Complete
removal of old sealant is not necessary. Permanent repair by direct
support, or higher category of maintenance, should be made as soon as
possible.
