Yellowed Lady Dior patent bag original-colour restoration

1. Cleaning: Use the pump-foam Leather Stain Cleaner to clean surface dirt.

2. Deep stain and dirt removal: After air drying, use a lint-free towel with 95% alcohol (described in the source as anhydrous ethanol) to rub the patent leather firmly, removing embedded dirt and stains to improve colour-coat adhesion.

3. Base colour: First spray a separate light, thin coat of Adhesion Resin to improve bonding. Mix Smooth Leather Resin and High-Strength Colouring Resin at 4:1, tint with standard colour paste, add about 10 drops of Enhanced Curing Crosslinker and spray evenly for coverage. Important: allow it to air dry completely before the next step; otherwise mottling or layer separation and peeling may occur. In summer, hang to dry for at least 3 hours or more; in winter, overnight is preferable.

4. Clear topcoat: Mix Super Patent Leather Clearcoat and Clearcoat Thinner at 1:1.5. Stir thoroughly, leave for about 5 minutes for bubbles to settle, then pour into the spray gun and spray.

5. Application notes: Use medium air and a somewhat high fluid setting, moving the gun steadily to wet the surface without runs. Avoid stirring up dust, which can cause defects. After spraying, hang for about 8 hours until surface-dry and touchable. Complete drying requires 24 hours.

6. Finishing touch: Wipe the whole bag with Patent Leather Polishing and Feel Paste, then polish for a clear, wet-look gloss.

The source states that the finished patent leather performs like the original finish, resists solvent wiping and does not become tacky again.
