Nano Paint Protectors/Window Rain Repellent
Someone has told me I should buy a 'nano' paint protector spray for the paintwork & alloys, & also a 'nano' rain repellent spray for the windows, including the windscreen, before I take delivery of my new 530e in a couple of weeks time. I have no experience of these 'nano' products & wonder if anybody has any advice & experience of these type of products. I don't want to use products if they could potentially have a negative effect on the paintwork, alloy wheels & windows.
