Spent today giving the zed some attention using all these:
The Autoglym roof stuff is brilliant and as an added benefit, seems to have helped my stiff roof too. Previously, it would need a little push for it to click on or the red light would flash. After cleaning and protecting it, it goes down a bit further and no flashing light, result.
Was very impressed with the G3 clay mitt, much easier to use than a clay bar and great results. Cleaned prior to this using the 2BM and cleaned again after using Optimum No Rinse.
Finally used to scratch remover on some small scratches , works well on little scuffs.
