Thanks. Been looking at the clay mitts that are very highly regarded. Some videos on Youtube show a guy washing his car with one of these and they remove all manner of gunk.

I have lots of tar spots on the front of the car, bonnet, mirrors and the sides of the doors. It is time to clay it for sure, certainly on those areas and I might as well do the whole car followed by a polish and a wax. The F11 does not need deep cutting, just a very fine polish will do it. Then a good wax on top of it. I will do one panel at a time to experiment.

I am thinking of getting a DAS6 Pro polishing machine. My Z4 needs to be deep cut to restore the paintwork so the machine will be well used. I might do that car first to test out the procedure since it is my garaged summer run around and only worth a few grand so it does not matter so much if I seriously mess something up.
