Full kit of everything you need to re-dye your Rover 75 Deep Sea Green steering wheel or seats. 100ml of Prep (removes oil, grease and original dye), 50ml of Neptune Blue Colourant/Dye and 50ml of top coat Sealant. Computer matched to original clean, unbleached and unworn leather. Full instructions included (even in French). Looks amazing and totally enhances the appearance of your car. I have purposely chosen colourant with separate sealant, this is much more durable and hard wearing than the all-in-one type colourants. 
Also have Rover 75 Sandstone, Smokestone, Aubergine, Neptune Blue, Rover 75/MG ZT/ZR/ZS Dark Charcoal/Ash Black and Rover 200 BRM Red.
I'm an MGR enthusiast and this is all I do in my retirement. Sourced the colourant/dye for my own cars and was bombarded by fellow owners to supply to them. I am not a company or anything like that, only someone that can provide what I looked for for years.
