Bought this stuff intending to do it when it arrived but that was at least 18 months ago

And happy with the results. No idea on its restores/protects claims but it certainly cleans well. The white stripes on the jacket are a pig and it worked well on them with a bit of elbow grease. Harder to say on the black as you can't tell but the leather certainly has a bit more of a shine to it. The difference between 1 arm and the other was really noticeable half way through.
At somepoint might take the jacket for a professional job of cleaning/feeding as I got it in 2008 but happy with that for now.
