Range Rover Sport
The whole point of the product is not to dry though...
if it it's rinsed properly it will not leave streaks as there's nothing to streak. Sheet the water off and jobs a goodun. All I can think of is majorly s**t water left in the crevices leaving marks.
To be honest I cant see it being that?
Is there a chemical that would make it do this if the bottle was in direct sunlight? Maybe could have gone 'off' while cleaning the car? Cant see it being the drying of it as surely it would be more in a circular pattern rather than streaks going down the car?
Either way, i'll give it another clean tomorrow. It was only £10 so nothing gained and all that...
