I usually wash my cars at night to help cut down on the water spotting.

Do these $200+ water filtration products I see advertised work?

 

YES, they do.....buy the one that moe sells.....just over $400, but works EXACTLY as advertised.

 

There's only one unit on the market that ACTUALLY works: CR Spotless.

 

On a side note about lighting.

It's key to remember that each type of lighting is a different shade. measured in Kelvin. Different ranges of light will mask or reveal different types of marring. When detailing it is imperative that you check your work with several types of lighting.

IE hps, MH, Sun Gun, Xenon, Halogen, 4200k flourescents etc.
