My Z4 seats have seen better days as it seems that the previous owner worn them in too much fading all the dye out.
I bought dome dynamix dye which cost me £35 but I only got 65ml which was no where near enough, plus didnt go on too well.
So I bought some Scuffmaster form Liquid leather which was only £19 for 250ml!!!! I spoke to an expert detailer who is well known on Pistonheads for his work on exotica and he told me not to apply the paint neat [like the manufacturers state] but to water it down quite a lot then apply a load of thin layers.
I managed to get my passenger seat done today! Took me around 7 thin coats.
I now have to do the drivers side and the hand brake.
I didnt do a before on the pass seat but it looked identical to my drivers seat:-
This is how it looks now [before conditioning as I have to wait a day or two before applying].
