i used it to dye my cherry red color Dr. Martens 8 hole soft leather boots into black. when i do some preliminary steps to remove coatings on leather, i thought i used pretty enough deglazer and thought it's done, but now i regret that i should have put more deglazer and remove those coatings even more carefully. Anyways it became black and i washed it with my horse hair brushes and air compressor in my shop, and it looks pretty decent. Angelus seems quite good at making these stuffs, and it looks better to get their stuffs from their website, not like Amazon or Ebay.
