 (k)  Apply the DC 93-006-1 (aerodynamic) sealant to the space
 between the strut fairing and the extension ring, as shown in
 Fig. 601.  Make the sealant smooth.
 1)  Let the sealant cure for 10 hours.
 NOTE:____ A ten hour cure time is for usual conditions of
 77 |2°F (25 |1°C) and 50 |5% relative humidity.  The
 cure time can be made faster if you flow warm air
 (not more than 120°F [50°C]) along the sealant.  You
 can also make the sealing surfaces warm before you
 apply the sealant.
 Airplane operation is permitted after a cure time of
 4 hours.
