GENERAL
Decals
For proper adhesion of decals, all surfaces must be clean and free of wax, oil, etc. Porous surfaces must
be sealed. Sand and clean rough surfaces to remove any residue.
A. Paper Decals
(1) Installation
Soak paper decals in water 1 to 3 minutes. Place one decal edge on receiving surface and
slide decal off of paper backing. Blot water around decal with a soft absorbent cloth. Remove
bubbles trapped beneath decal by wiping carefully towards nearest edge with a cloth. Coat
decal with clear varnish to protect from deterioration and peeling.
(2) Removal
Remove paper decals by rubbing with cloth dampened with lacquer thinner. Use lacquer
thinner sparingly if decals are applied over painted or doped surfaces.

decal until all air bubbles are removed.
