Bought a leather jacket from second hand store. It was pretty wrinkled and crunchy in places. It said washable leather on the label so I threw it in the washing machine. After using 3.3 and fat liquor it's looking better but the leather is still a bit stiff and wrinkled in some parts. Tried stretching it out but no avail. Used a whole bottle of 3.3 and most of my fat liquor. Should I move on to protector or does it need more fat liquor. Material still isn't flexible
