Not today, but this week, took the car to 'The Wheel Specialist' in Leeds for a full clean and recoat.
They seemed pleasantly surprised that not one wheel had ever been 'kerbed' (I wouldn't do that to my motor!!!!), but at nine years old, the inboard sides of the rims were losing their paint, and the outers were dulled (I suspect previous owners may have had the cheap'n'cheerful handwash brigade use their acid spray guns on them.
However, the end result was excellent, great finish, there appear to be no flaws in the coating, and, what's more, received the 15% LOC discount !
Good 'workmanlike' business to deal with too.
