Hey guys. My 2003 altima recently got grainyspotsall over the vehicle. When i wash it comes out clean and clear but when you rub your hands through the paint is grainy. What can i use to remove IT, ANY KIND OF WAX??

 

sounds to me you need to clay bar your vehicle. Here is one article with instructions...

After that you can use a wax. I use Turtle wax "1-step wax & dry". Just wash your car, then rinse and leave water on the car. Spray the wax on the wet car and wipe. Easy to use and leaves a great shine!

 

Are you going to polish it by hand or by machine? Yes clay bar would the first step before polishing it. And for a polishing compound M205 or Meguairs Ultimate compound be a good brand.
