I have a black 2003 350Z. Original black paint was in GREAT condition until last summer. Had it parked at my place of work and it most likely got wind sprayed with white paint from a next door neighbor in the complex. Now entire car including windows have a very fine dusting of white specs. Tried clay bar, does nothing for it. Suggestions?

 

What grade is the clay bar you are using? It should come off with a medium grade clay bar and some quick detailer spray or clay lube. You can use lacquer thinner on a micro fiber (be careful) to get it off then polish the car back compound, finish polish then finish with a paint sealant or wax. Take it to a auto detail shop if you don't have time.

 

This neighbor is still alive? When my '88 Henna Red M3 was just two weeks old I came around a corner and drove into a huge cloud of white paint as a guy was spraying his POS Mustang by the side of the road. I called the Sheriff, had him take a report, and then sued the guy in for $3500 (and won). Took almost 2 years to collect the money, though, and looking back, I wish I had just beat the crap out of the guy instead. I'm not the violent type, but that sort of stupidity is sometimes just too much. I ended up taking the car into the dealer's body shop, which happened to be a very good shop, and they made it look like new. They used a machine polish called Liquid Ebony.
