My 110 is now super dry underneath and I am thinking about getting rid of the crud and applying stone chip or paint. What is the best thing to use to get rid of all the crud or is it a case of wire brush and long periods of getting dirty?
Get it down your local lorry wash place and get a "Pre MOT" underbody clean, those guys have kit that will strip ALL the crud off and you will just have to leave it to dry again.
