Leather Shoe Polish Can I Use Shoe Polish To Repair A Leather Jacket???

Can I use shoe polish to repair a leather jacket??? - leather shoe polish

My friend is flying from Europe to the United States and in the morning there is a abbrasion (wear) Brand (about 2 cm wide) in his leather jacket with a heavy backpack. This has abbrasion skin in the area of lighter color than the rest of the layer. I have one of those leather repair kits that you see on TV. Has anyone ever tried to use shoe polish in a fur coat on? Or if in the U.S., you can use a repair kit leather. Please give the names of the shops.

And one last question. I have a white leather jacket with a blue pen to mark it. I tried the "Quick n Brite stain remover and pen loops. No sale. Any suggestions? If you rub damage the leather.
