You done the zed before?  How bads the paint? 
  
Nope, never clayed before... and only polished once.  To be honest the paint is really good - there are no swirl marks at all, although there is a lot of tar.  When i rub my fingers over it, the car feels rough. 
  
Oh well, plenty lube and a bit of time!  I never wear a watch when I'm cleaning or detailing so how idea how long anything takes.  
  
I'd say the claybar took less than 2 hours. Its easier than polishing IMO. I'm chuffed with the result but it did show up the stone chips on the front bumper. 
  
Will re-do it the day before Wales (as long as its dry) which I'm actually looking forward to   
  
I need to join in with that competition though as I've lost a wheel nut on the rear
