Regarding my Mk4 estate - is there any way to improve the aerodynamics so that the rear windscreen doesn't continually need wash/wiping when you're driving along in rain / drizzle? It's the first part of the car to get dirty after I've washed it, and with all the clag on the roads at the moment it's annoying to say the least that you can't go 3 minutes without washing the rear screen!
I used to have an old Honda Accord Aerodeck (long may she rest), and the aerodynamics of that meant at anything over 30mph in whatever weather the rear screen stayed nice and clear!
Also, as there is a large amount of nice shiny body coloured bumper before the boot lip (nice designing, Ford...) - is there anything available, such as a clear film (like a smartphone screen protector) that you can get to stop it getting scratched?
any help, much appreciated,
