Some of the leather inside of the car was starting to look abit warn, So im going to re-dye it. I prep the leather before dyeing . Giving it a very good clean, using a leather deep cleaner to open up the pours of the leather. then using leather prep, which is just acetone. to remove the leather finish. not the colour just the finish. Finally alcohol cleaner which is isopropanol or IPA. I realised this after buying the kit haha As I use both these chemicals in work to clean stuff, and I know the smell a mile off. Then spray the leather using leather dye a mini compressor and a spray gun on
