My Peugeot seems to be really attracting the crud off these Devon roads. I’ve never known a car to be such a magnet. The Skoda seems to fend it off. So can anyone recommend a wax / top coat that will act as a repellent and keep it at least half shiny. But, I don’t want anything I’m going to have to spend hours on applying, not with my dodgy knee. I’ve seen ad’s for ceramic “polish”, is that any good ? I’ve used Auto Glym in the past, but I’d like something longer lasting.
