I wish I had taken pictures of the retouch work I've done.

I did it with the Leather Magic recoloring kit. Unfortunately the light grey was too bluish in tint and didn't exactly match, so I bought their Lotus White color and mixed until the color matched perfectly. Went with them because I heard it was more friendly to a sponge application.

One thing that really troubled me though was the prep product seemed to take off some color of the existing leather, not sure if it was color that was already about to go or if is too strong for old leather. Also found that the prep product can remove the new paint even 24 hours later, and am worried whether it'd hold up over time.
