Leather Dye

[Murdoch]

Hi everyone. Steve here from York, one of the newer members.
Myself and Bulldog Bri are working on restoring a Merlin, and currently have light grey leather seats that we would prefer to be cream.  Rather than paying for full refurb, I have found a couple of places that sell leather dye kits from about £50. The photos look pretty impressive, but who knows what the reality is .
So, anyone out there have any experience of this sort of stuff?

Thank and kind regards
Steve
