My gray interior has few scratches here and there. Can I buy some kind of touch up paint?

 

IMO I wouldn't use paint I would try a local automotive upholstery shop, repairs like that are inexpensive and when done right look like new. If its leather interior parts that need touching up they can match the leather dye for you.

 

I bought touch up paint from leather world technologies and it worked fairly well.

 

i have an 05 carrera with sand beige interior i had a bunch of scratches in my door right by flip up storage. drove me friggin nuts. i took my ashtray to home depot and the color matched the color and i got a small can of there premium paint. it actually matched perfect. i used a foam brush and it matched the texture well too. mabey give it a try on some spot out of the way 1st. worked great for me.. and im a fussy dude....i didnt use on the leather,,, just the plastic painted parts..
