@Mr Red – To put it shortly,there are certain steps, that enable to achieve such effect:
1. Renovator – if you want to take out the previously applicated cosmetics from the leather; if polishing brand new ones, might be skipped
2. Shoe grease – smoothes the leather and protects against the water
3. Shoe cream – helps balancing the colour
4. Hard and smooth paste one after another repeatedly, then one drop of water and silk pocket square or nylon tights – enables them to shine.
