1. Paint your model with gloss paint (highly recommended) or cover your model by gloss clear and make sure that the decal is FFA-compatible. THE MODEL SURFACE MUST BE TOTALLY SMOOTH AND GLOSSY! The decals have FFA logo or covered by safety paper. Be carefully with the FFA-decal and store it with the paper only.
2. THE MODEL SURFACE MUST BE TOTALLY SMOOTH AND GLOSSY! The entire sheet is covered by clear film. Cut an element and use it as a common decal. Put some water on model surface before transfer an element. Shift the element to model surface, pay max attention to smooth out it with wet cotton stick. No a bit of air bubles under the decal! The FFA technology works so good only with water, without any special liquids.
3. THE MODEL SURFACE MUST BE TOTALLY SMOOTH AND GLOSSY! The best result for removing the film is during 2-4 hours after the element has been transferred. It possible to remove the film after the period but smallest elements may be damaged. Pick up edge of the film by a small nail or modeller's knife. Remove the film gently
IMPORTANT!
No a peace of a miracle in FFA technology - if works everytime if the surface is smooth and gloss. BUT! To smooth out the decal on the model surface is SO VERY IMPORTANT STAGE. Spent several minutes to smooth out. Remove all air and water under the decal.
It's example of insufficiently smooth out the decal. The paint was removed with film.
