C. Positioning of "BSB" transfers (Figure 202)
1) Sequences of operations
Area preparation :
a) Mark the place of transfers to be positioned.
b) Carefully clean area with a C gasoline (TB 11-918) or F gasoline (TB 11-919) soaked cloth.
c) Impregnate the area with a sponge soaked with special C decal solvent (TB 07-903).
NOTE : In case of decal solvent overflowings or runnings, immediately clean with pure water.
2) Work on the aircraft
Before positioning the transfers on the aircraft, plunge transfers during 15 to 20 seconds in the following mixture :
— C decal solvent (TB 07-904) : 1 volume
— Tepid water [30 to 40°C (86 to 104°F)] : 1 volume NOTE : Use a new prepared mixture for each aircraft.
3) Positioning
a) Fit the transfer over the foreseen exact position with letter marks facing the aircraft area.
b) With hand, put one of the edges in contact with the area and hold the other transfer edge stretching it lightly to avoid folds.
c) With regard to the coordinates indicated on the support paper, complete their vertical and horizontal positionings.

e) Flatten by firmly pressing on the scraper, by successive passages overlaying themselves, the transfer part to be applied and check it for no air bubbles and folds and for its good adhesion.
Wipe water runnings with a sponge, as the work proceeds.
f) Wait two minutes and remove the support paper.
NOTE : In spite of taken precautions, should air bubbles confined between the film and the application area appear, perforate these bubbles with a needle, and press with the nail or with a plastic scraper to drive the air out.
