Any product you would recommend in order to restore the black colour of my leather? As strange as it seams, the colour seams to "peal off" and there are a few spots were my leather is back to its "natural colour". I suspect the leather was restored in the past with a dye that does not stick. Also I am using a mix of turpentine and mink oil to keep the leather supple, maybe this mix was too much for the dye. A bit of thinner does smooth the paint cracks, so my plan is to clean this mess and apply a new dye. But i'd rather apply a product that penetrates the leather rather than a coat that will crack again.
