Safe drying
With the water all rinsed off the car, dry the car safely. We'd recommend either the Twisted Pro Sucker or The Big Green Sucker with a few sprays of Boss Gloss for the job at this stage.
If you normally use After Glow to dry the car, this is also fine, but the extra advantage of After Glow with its protection will be removed with the next step here, so just stick to either the Twisted Pro Sucker or The Big Green Sucker with Boss Gloss.
