Saddle, thick boots, old belt, fine ladies' shoes, handbags, leather gloves, jackets, leather seats all my husband has already dealt with this leather care and is enthusiastic. Hard leather is soft and supple again. Leave on for one thin layer at moderate temperatures as long as possible, polish, ready. Very neglected leather can also be treated 2x consecutively. That's better than a thick layer in any case.
Suede I would so but do not treat any more than patent leather shoes. For the color restoration, however it takes a correspondingly colored product, because even if the color of the commission appears more intense, so this impression evaporates again when the leather care is drafted.
