black leather seats. During the cooler months here I repair those areas using some black leather shoe polish and then buff it out well with an old rag. If things are really bad - repeat a few more times. Next day or so I go over everything with leather cleaner/conditioner.
On my Z the area that most needs this is the driver side bolster and the piping on the bolster edge. I prefer to do the polish repair in the cooler months (Spring/Fall) to reduce accidently getting the seats too hot and having a spot of polish get on clothing. Have done this method the last few years -- works just fine.
