    1. sanding of the rough edge;
    2. first application of painting product to the edge;
    3. first gelling;
    4. post-gelling sanding of the edge;
    5. second application of said painting product to the edge;
    6. drying;
    7. final post-drying sanding;
    characterized in that
    - in steps 2 and 5, the application of said painting product to the panel edge occurs through two layers of painting product applied in a wet-on-wet close succession using only one vacuum head (23, 23') applying two layers of painting product in each step;
