Wasa thinking in your thread, that that looks like new
yeah i was told about a year ago by the bloke in my local motor shop.
he said just use a sponge and rub it over. i tried it with a cloth but sponge works much better.
have never used anything els since and never will as it works so good. and good on your tyres aswell
it also give is a nice shine and it glistens in the sun and instantly gets rid of any dried wax so best to di it as the last thing you do after you rub the wax off your paint.
