I have 845 with me but I am reluctant to use it on white color.
The 845 wax is a like a light yellow colour so suits these cars. If put on a black car you get a slight yellowing effect - too much and the streaks might make it end up looking like a bee! Do the maths for white.
Similarly, using a wax for dark cars (like dodo Purple Haze or Natty's Blue) will make your light car appear with a purple or blue haze. That is really bad as more people will think your car is dirty and some scientists might even think you car has been hit by particularly intesnive solar radiation and try and quarantine you to make sure you havent undergone cell mutation from the super strong UVa rays.
The orange coloured waxes are even worse! So never ever use the wrong coloured wax on the wrong coloured car.
