Wetsanding, Colorsanding & Dampsanding

Just to note, wetsand and colorsand, or wetsanding and colorsanding, are interchangeable terms.

The term color-anding came from the time cars were primarily painted with single stage paint and as such when you sanded them dry or with water you would see the color of the paint coming off the car, thus the term colorsanding. If you were wetsanding a pigmented or single stage paint, your water slurry would be the color of the paint.

Wetsanding is just a term to describe sanding automotive paints with water. If you're wetsanding a single stage paint you'll see the color of the paint in your water slurry as you sand. If you're sanding a clear coat finish your water slurry will be a whitish color as the sanded particles of clear paint are not clear but whitish or opaque and thus the water slurry will have a whitish appearances to it.

Dampsanding is simply a variation of wetsanding except that you use less water with sanding discs designed for use with a process that uses less water. The water slurry from dampsanding will either be whitish if you're sanding a clear coat finish, or the color of the paint if you're sanding a single stage finish.

Water Slurry
The water on the surface of your work area that suspends particles of paint removed off the surface from the abrading action of your sanding paper or sanding disc.
