A case study each day: practical process sharing

Prada yellowed white shoe-edge restoration
1. Cleaning: Use the pump-foam Leather Stain Cleaner to clean surface dirt.
2. Light finish removal: After air drying, use a lint-free towel with 95% alcohol (described in the source as anhydrous ethanol) to rub the shoe edge firmly, lightly removing finish to improve bonding of the colour coat.
3. Masking: Protect areas that do not need colouring with masking tape, preventing contamination and additional repairs.
4. Colour coverage: First spray a light, thin coat of Adhesion Resin to improve bonding. Mix High-Strength Colouring Resin, High-Efficiency Matting Agent and standard colour paste, adding about 10 drops of Enhanced Curing Crosslinker, then spray evenly for coverage. Defects are conspicuous on white, so avoid a hairdryer where possible. Do not heat with a hot-air gun: high temperature can cause renewed yellowing.
5. Final sealing: Mix Odourless Wear-Resistant Fixative with High-Efficiency Matting Agent and add about 10 drops of Enhanced Curing Crosslinker. Use medium air and medium fluid; about two coats are stated as best.

Understand the sequence and decisions
Additional explanations based on this case’s original record.
Prepare and mask the surface, restore white coverage and apply the finishing coat.
Make masking part of the process
The source lists masking as its own step to protect areas not being coloured. Keep it in the overview.
Source reference：MaskingConsider cleanliness and colour together
The source warns of defects from blow-drying and prohibits hot-air gun heating. Preserve the concerns about dust and renewed yellowing.
Source reference：Colour coverageColour and fixing have different formulas
The source specifies separate materials for colour and sealing, plus a number of finishing passes. Check each rather than combining them into one formula.

Can a hot-air gun speed drying of the white edge?
The source explicitly says not to heat with a hot-air gun because high temperature can cause renewed yellowing.
