You can dry the car then use itGuys have a bottle of Sonax BSD which seems to be well regarded but I think I'm doing something wrong as I'm not getting a good finish.
After drying the car how the hell do you use this stuff correctly?
Cheers.
Or use it as a drying aid
Both ways you spray it onto the car


i tried to get it off with white vinegar it would have taken hours to get it off, then i remembered someone telling me ages ago that wd40 is good at getting rid off things, tried a small amount and i cant believe how good wd40 is, it took it off in under a minute.
