It's a good, economic solution but you have to remember it is NOT dye (despite any literature/advice)
It is only PAINT, so as a consequence it will wear off & crack in time. It also seals the leather surfaces so any hide food or cream cannot moisten or feed the leather & it will dry out from the reverse side. This is why painted leather is more prone to cracking like death valley.
Paint is the beginning of the end for any leather.
