Wet vs Dry Sanding
This ball was sanded with the same grit, left-dry sanded, right-wet sanded.
Wet sanding produces a more sheen like finish, water acts as a lubricant to a point so the cutting isn't as aggressive.
Also wet sanding helps keep the dust and friction heat down, the water also helps reduce buildup of the cuttings in your pad/paper which let's them cut better and last longer.
Wet sanding is pretty much the standard when using a home spinner.
Dry sanding is a bit more aggressive and will give you a duller surface. But you get more friction which generates more heat and the pad can load up which can reduce the effectiveness of the cutting.
