i have an '03 with a black interior and i used this meguiar's thing for cleaning and shining the interior...
and it looks ok for a day or so..but then afterwards, my dash looks really dry and chalky almost..

any suggestions for making it darker black and clean looking?
shoe polish???? idk

 

Which meguiars thing...and I applogize for my lack of knowlege but is it Vinyl, Leather, Plastic...?

 

Try 303 for a matt finish or Vinylex for a bit more gloss.
