I just purchased a used 2005 RX330 this week. The vehicle was kept in great shape and Lexus has all the service records for the vehicle. I cannot see any indication it was ever wrecked or had major paint work. The seller was upfront about some work that was done on the front bumper but never mentioned any other paint work. I spent a few hours last night reading through all of the car washing advice. I set out today to wash and wax the vehicle starting with the 3 bucket method. When I finished waxing the vehicle I noticed one area of the car that was not smooth. It was roughly the 1-2" below the driver's front and rear window and the area on top of the driver's window. If it was repainted it blends perfectly and it still shines. I have included two photos. They were taken on an Iphone.
I tried the search feature and a clay bar seemed to be mentioned as a possible solution. I saw one they had at wal-mart but I know there must be a better product. Is there anyway I can screw up the paint using one of these clay bars? Any other ideas on what may be causing this rough area? The rest of the paint is smooth. Thanks in advance for any tips or tricks.
