It took the better part of a whole saturday to do my old BMW(god rest her soul
) It was probably a good 4-6 hours to do the car with the clay. I then proceeded to 3 step wax the entire car as well in the end I was probably in the drive for 10 hours.
It was well worth it though she looked dead sexy when I was done
The rover gets clay on it all off road
the time but I have never done a clay blocking on her, hell I'm doing good if I rinse the mud off.
