4) Remove any staples applied to the area to be reworked.

5) Evaluate the extent of the skin detachment and, if possible, partially intervene in the affected
area with a localized repair or confirm that it is necessary to completely remove the skin from
the entire section of the dashboard.

PARTIAL REPAIR
1) Using a cloth, isopropyl alcohol, and an upholstery spatula (recommended product: Socomore
Sacosat A 2501 cleaning wipes) depending on the type of detachment, carefully remove any glue
residue from the dashboard support, the polyurethane foam support, and the underside of the
leather itself. Using fine sandpaper, sand the area of the dashboard affected by the rework to
ensure a better hold of the adhesive.

Using a heat gun at a distance of no less than 30 cm, gently heat and pull the leather to make it
regain elasticity and ensure correct positioning on the dashboard support.
