I hate sanding, especially when my sandpaper wears out and I don't have any more so I have to keep using the same sandpaper which is taking away less and less material with each pass.
Wetsanding helps your paper last a bit longer. It stops the grit from getting clogged as fast. I still spent a week wetsanding Mulder's Nipples, though. There aren't any real shortcuts that make it as pretty as good sanding does.
