I have a cargo van with windows in the rear and side doors, got spray paint from Wal-Mart, painted black for max light blockage then white to match exterior paint. A lot of cities have laws about tint, police can't see in but people inside can see out(dangerous for cops), but I haven't had any problems with paint, vans come with no windows. <br /><br />I just back into parking spots so I don't have to back out into drive.
