Ahh black looks so good when it's clean!
Claying bores the hell out of me tbh but it's a necessary evil at the end of the day!
As long as you've got a DA, keep it on a low-ish setting and don't stay on one panel (or section) for too long you should be fine tbh. I did the old dears Ibiza a little while ago and it came up nicely... even if she has been down the back lanes and got it filthy with the Labrador in the back since!
