Fallout guarantee it, de-ironizer is your friend here! Spray, let it go purple, rinse. Like Jimble said don't let it dry!
mate, i'm really new to this so if you please be a bit more specific. De-ironizer meaning?

also copy-pasting my earlier two questions though (the first may sound really silly):
1. claying: is the clay we are supposed to do the car with, the same as the one little kids use to play with??? And does it matter what color it is?
2. Would you suggest any of the following lubricants (got them from the MK5 detailing forum)?>
Meguiars Quick Detailer Spray
> Meguiars Last Touch Detailing Spray
> Meguiars #34 Final Inspection
> Clearkote Clay Lubricant
> Pinnacle Poly Clay Lubricant
Off to enjoy the not-so-sunny day now
cheers
