The issue with water is rust. The water will collect in the exact place I forgot to paint. Here in Florida, water doesn't evaporate as fast as say, Nevada, my home state. Though it is a mute point since I went ahead and washed the truck with water and soap, then used my compressor to blow out as much water as I could out of the nooks and crannys, then wiped it down with a towel, then wiped it down with a wax and silicone remover. Overkill? Probably. But all I care about is starting the sanding process, yeah!

What are the reasons that wet sanding is superior to dry? Less clogging of the paper?
