i use meguiars clear coat body scrub, followed by a coat of wax.
I would avoid using anything likely to have any form of fuel/solvent etc as it will strip off any wax and could discolour plastics etc.
in using the CCBS on the whole car you get rid of all blemishes, tar, sap and light swirls too - following a good coat of wax your MINI will look the biz.  Dingdangdoo! |
