 PRESSURE-SENSITIVE DECALS - REMOVAL/INSTALLATION
________________________________________________
 1.  General_______
 A.  This procedure contains two tasks:
 (1)
Removal of the pressure-sensitive decals.

 (2)
Installation of the pressure-sensitive decals.

 B.  Apply external decal sections in a sequence where the ends make an overlap downstream from the line of flight.
 C.  All exterior decals require edge sealing using paint or an edge sealer unless specified differently.
 D.  Clean plastic film decals with naphtha. Do not use adhesive activator.
 E.  You can remove air bubbles in the eight hours after you apply the decal. Make a small hole in the decal film with a sharp pointed instrument, at the edge of bubble, and push air out through the hole.
 F.  You can also install interior decals with the same procedure you use for pressure-sensitive placards (AMM 20-10-14/401).

 (a) To remove decals with heat, do these steps:
 1)  Heat the decal to approximately 120°F until the adhesive becomes soft.
 NOTE:____If you use too much heat, the decal will melt. If the decal melts, remove it with solvent.
