Can i be the first to mention that I hear that gliptone is rather good?
Surely the polish will rub off on to clothes and the sort?
i read somewhere (on a Z4 forum?) that you can use black liquid shoe polish on black leather and it works quite well. can't find the link tho, but i've been wanting to try this
I did the seats in my old Volvo 850 estate with black shoe polish. Worked wonders!
