I have no idea on the mechanics or chemistry of it but I've had no scratches from using it on my last 3 cars including this one.
Obviously if it's caked in mud I'll jet wash that off first.
My image speaks for itself, in fact, here's a close up, this car has had the dry wash treatment once a week for 5 months.
In fact, and I know it's personal choice, but I'd say it seems better than a 1 bucket wash and could possible only be bettered by a 2 bucket system with filters.
Here in Telford the water is hard and leaves terrible lime marking on Panther Black, but this stuff eliminates all the above and there's no scratches or swirling.
Small stone chips usually leave behind protected metal, it's important to know if the stone went through to the metal or not.
They can be pretty well fixed I found a cocktail stick very useful rather than a brush, and I'm a convert to Halfords matched paint.
They match it from your paint code.
"Ford has fitted the Black Edition with sportier suspension than the standard models. The Black’s springs are lowered by 10mm and are 12 per cent stiffer at the front and six per cent stiffer at the rear."
I got a free Dash cam app for my iPhone and tbh it's as good as the standalone one I had in my last car.
Sits in a screen cradle and I take it out when I leave the car.
I agree the Save option doesn't work, but it DOES actually save recordings.
The Golf (if it's a 1.9 diesel) is also a damn sight uglier, dirtier and smellier.
That's not an insult but a truth.
Why, some old oil burners could probably run on chip fat too... Mmmm nice.
The point you miss here is that modern technology has allowed Ford and others to create very small capacity engines that, to date, are zero road fund rated, will never need a cambelt changed, are fantastically agile and fun to drive, are pretty quick by ANY standards and can STILL give almost diesel like economy, not forgetting petrol per litre is so much cheaper than devil oil too.
