update , Tried clay bar today for the first time, WOW Cant believe the difference it made, i only did half the bonnet. Feels like polished glass.
Washed and dried the car with megs car shampoo, then two goes with the clay bar and megs sloppy stuff then two goes with the DA using PB ssr2, then polished/wax with megs carnuba. very impressed, need to do the whole car now tomorrow...cant believe the difference despite all the hard work.
pictures to follow tomorrow if it stops raining
BTW, thanks for instilling in me the confidence to do it !!!
