Here is another shot of Sams drivers seat.
All I can say is follow the threads and buy the cleaner/sealant and Anthracite dye from
Buffalo leather. I can of sealant, 250ml max of dye and 250 -500ml of cleaner.
All the links are are the thread as is the instructions how to do it.
like I said the distance makes it virtually impossible for me to drive as I have Sciatica
otherwise I would suggest me doing it.
It is a tedious job as you have to painstakingly use 1200 grit gently on the scratches to remove the edges of the scratches.
Then using a tooth pick, drop dye along the scratch. If you rush it, it will look naff so make sure you have no destractions.
Let me know when you have the 3 items as there is no point in continuing until you have them.
I will then assist you and talk you through each stage.
I suggest you get the 500 ml of cleaner and deep clean both seats, as judging by the rest of the one in the picture, there is a lot of ingrained grime:)
