2018 4c and Stelvio
I can't drive for 5 minutes without the rear becoming dusty. The exhaust doesn't create much, just seems like road pickup/drafts. Anyone have a solution?
my Option # 1 = 100% EffectiveAirflow / particles over plastic panels. Like rubbing a balloon, perhaps?
I notice a lot of exhaust soot on the back of my white car, so that is part of it. But certainly any dust on the road gets lifted up and enough is deposited back there too.
Not sure what the solution is. lpspeedster's option # 2 might be worth a try.
It's the car's aerodynamics working - the ductail creating a low pressure area behind the car, sufficient to evacuate the air from underneath the body. Unfortunately, it lifts up any bit of road particles that have been disturbed, with it.
So if dust is getting sucked upwards then this is because of low pressure being created, meaning we have downforce ? This is a good thing then, over a certain speed I’m sure we start feeling more uplift though .The underside of the car acts as a vacuum cleaner. No one has mentioned the dust that collects in the engine bay, especially on the flat area on the engine side of the firewall.
There’s the problem will electrostatics on the paintwork too.
If you’ve ever followed a 4C on a slightly dusty bitumen road it might remind you of the Peanuts character, Pigpen. The dust isn’t only disturbed by the wheels but by the whole low, flat underside. The dust then gets sucked (I know there’s no such thing as ‘suck’ in physics) up into the engine compartment.
Considering that looking at Rosso Alfa paint without wearing sunglasses will leave swirls, yeah, I bet any form of duster will start to affect the clear.Unless your car is fully wrapped, it’s definitely scratching. Not gouges, but it’ll leave swirls in the clear coat.
