This is my own version of a rack for storing and drying MicroMesh pads during and after use. I made my rack with drain holes in the bottom so it can be set on top of a towel and catch the water when wet sanding with the pads. I put a large hole in the other side so the pads can be easily removed in a stack when finished and ready to dry the pads. To use just take the top pad and sand. When you're ready to move on just put that pad in the other compartment and grab the next pad until you have reached the highest grit pad.

Side note: Never use the same water for more than one grit when wet sanding. The larger particles you have just sanded off will get into the water and will cause scratching of your project piece. It's better to use a spray bottle to wet the pads and rinse the project piece than it is to dip the pads in a container of water. When you are finished sanding, rinse all the pads under running water and set out to dry. When dry you can store them in the rack on the left side.
