I have used this on my 2011 mx5, the seats were very dry when I purchased it. A couple of applications hasn’t transformed them, but it’s not premium leather to begin with. It does however feel as if the leather is being nourished. This is my second bottle. I would certainly recommend.
I have too many bikes, a range of designs, multi speed to single speed, steel, aluminium and titanium, but only one make of chain, KMC. Consistently excellent.
