My roadster has a few white marks on the hood (both general marks but also some 'stretch' points at contours as it's aged) which I'd like to re-darken so it's all a nice, deep black again.
Heard lots of good things about Renovo but be carefull as some roof dyes can soak through.
AG kit on mine and looks fine i only get the creases and white marks after having the top down for the day i find they tend to dissapear after washing the car but still a few marks as it is a soft top at the end of the day
