I've got a worn patch on a car seat side bolster. Its only 3 years old but
out of warranty and the only option is to repair ensitu (replacing is
impractical due to extornionate cost!).

Is there a DIY product I can use to resurface the leather? Its a matt black
finish so no colour matching needed its just getting it to blend in with the
rest of the side panel thats the issue.

Any suggestions?
