The roof is just covered in a layer of road grime that makes the flour stick instead of being blown off... There's probably not much actual weight in the dirt... However, maybe for sake of testing, I might wash the car...

I did however remove the VG array I had previously installed... Waiting on some data but it looks like a wash as far as efficiency goes...
