I am from Australia and have a 2001 holden vx ss commodore. The car has been looked after but it's looking a bit dull as the years have gone by. Today I did a wash with some meguiars shampoo with a small amount of apc to really get it clean. I then clay bar the car and then re washed with Megs. I have noticed some staining stubborn dirt that the clay did not remove. Also the bonnet seemed to have a lot of fine scratches and some swirls. Have not noticed them previously. I am working by hand and planned to go over the whole car with ultimate compound. I also have ultimate wax to go on over the top. Should I also use ultimate polish even though the car is white would this extra step bring back some oils shine to the paint.
Admittedly the car looks way better just after the clay and wash what's the best way to remove this stubborn dirt and staining. Is color x or ultimate polish a good step or should I just uc the car then follow with the ultimate wax.
