After seeing @Farquis shining Gs450h is always planned on getting my car corrected
they (autobrite) had it this week for three days, £280, and what was a car made up of more of swirls than I remember seeing, and multiplying every second look, was transformed into a rather nice clean car
two stage polish, some manual effort involved where paint has been repaired and was too hard for machining, and a water based ceramic coating
then within hours, my neighbours building work took effect, the car is now covered, or as I am now pretending, covert.
