What is the best product or treatment to use on my grey half leather recaros. Some of the colour has worn off the bolsters and steering wheel, Have tried the grey leather balm thats on Ebay in the circular flat pot but it's not a good match. Too light so I binned it. I seem to remember a 2 pot treatment that the Capri club was selling but can't see it advertised. Anyone had good results with it or something else?
