I recently scratched the passenger leather seat pretty bad.. to the point the orange is visible and was wondering what I could do to disguise or repair the scratches.
I'm thinking of using black shoe polish.

 

you could try that or get black leather dye

 

Another quick fix is to use a black "Sharpie" permanent marker. Also works really well on small paint chips where the white primer is exposed (if you have black paint...).

 

Similar problem. I have a 06' Grand Touring with perforated leather seats. There's a scratch about an inch in length and the orange is exposed. Anyone know if there's a fix for this or if any in the Los Angeles Area does a good job at this type of repair?

 

 

careful, sharpies tend to bleed, leaving you with a colored butt.
