www.nerta.com.au Anybody ever used this stuff, or even heard of it? At fist glance seems like another to good to be true product...basically just cover your car in foam, wait a few minutes, then wash it off. Wouldn't have thought it worth looking into, but some mates of my brothers use it - they are from out west NSW, have a few trucks and some decent cars (couple of xr6Ts, GS etc)and they swear by it, with the dust out there they are pretty full-on keeping their vehicles looking good... Made me wonder.
