Plenty of folk look after their paintwork. Some even look after the engine bay.
Never really seen anyone on forums 'looking after' the underside of their car.
Is it even really needed in that case?
The reason i ask is because <a> http://www.astraownersclub.com/vb/sh...=177240&page=2 has me concerned. Also <b> my last car was just about to be put down because of rust & it was only an 8yr old car, which isn't new, but certainly isn't what i see as "old".
Think the g/f had 'wax oil' put on her Polo. This stuff any good?
Just looking for what you knowledgable people use/would use & a bit of info on product / application / time between applications etc etc
Don't want to be a big sufferer of the rust :|
