Has anybody done it on here? I have had a browse on the net and have got a good enough idea on how to do it, but was just wondering if anybody had some do's and dont's for me on here lol. I intend to dye the rear bench and back from a A3 which is currently black and grey to all matte black to match the front Audi A5 seats. I have come across a seller on eBay who say they can colour match to manufactures colour code's so i intend on giving it a go. Thanks in advance for any help, Jonny.
