Purchased the Leather Colourant Kit, an Antique top coat, the Leather Binder and the Flexifil to use on a 26 year old chesterfield sofa. Followed instructions to the letter. I used the leather binder before using The flexifil. Both are very good products and did a great job of filling in the cracking on the arms of sofa. I found that although I did not colour match, the antique brown colour and top coat was a perfect match for my sofa. Seeing as I did not do the whole sofa, this was excellent as you cannot tell the areas that I treated from the original areas. Was totally delighted with the results. I would advise ordering a spare tin of gas propellant as I ran out and had to order another. Would definitely recommend both the products and the company. Duncan was available to give me any advice necessary. I must have drove him crazy with all the questions, but he never seemed to mind.
