I ordered an extra large kit with colour match for doing up a sofa, which had cracked at one arm and two of the cushions with the third showing wear. Very helpful emails from Duncan when I got stuck or wasn't sure how it was going. He responded very quickly. In future I would get filler rather than just the binder. I was kindly sent some free of charge when it seemed that was the problem. Its important that everything is smooth and level before you put the colour on. (I had to remove colour to go back a stage and that was fiddly). I enjoyed using the spray gun when I got the hang of it! I have plenty of material left to do the back of the sofa and a chair except for the propellant.
