Oks i work next to a train yard so theres a lot of freight train movement thought out the day and this kicks up a lot of dust which coats my car every week with a brown light powdery dust. When i get water on the car when the dust is on it, its almost like its water proof.
Whats best way to remove this ?
[my paint works a shambles needs a fresh coat of paint but thats going to have to wait so atm it doesn't need to be anything fancy, just want to get the dust off it]
Thanks
