hopefully weather permiting il be doing it this weekend

i jynxed last monday by getting all my stuff ready the night before

.
the clay bar is realy easy to use, first of wash and dry the car, then use the supplied lube and spray over the panel around a foot at a time, then rub with the clay

fell the paint with your hand and it should be smooth, if not repeat till smooth.
on closer inspection though, im thinking clay wont be enough, as the water marks look quite old

so some light compound and a buffer may be requierd .
cheers for the welcome, and il take as many pics as possible.
Dave.
