I had a very nice leather purse, which was colored light beige that was looking soiled after using it for less than a year. I tried random leather cleaners but it still looked dirty. That is when my friend recommended to me Fiebings Leather Dye. I applied two (2) coats of this in brown and it looks like a new purse. The zipper even dyed well. Try to remove any dye that makes contact with any metal parts before it dries, it even adheres well there. That just proves how good it is and I highly recommend it if you want painting leather.
