Wetsanding it's like this: You will get a high grit paper (1200-2000) and dip it into water.
When the sandpaper it's wet (like a wet paper) You get it and sand it on the body like you sand an ordinary part.
The result will be dull,with no shine,but will be smooth. After you do that,you use some compound on it,then it'll be shiney again,and smooth. After that I put the decals and clear coat. Then in the clear coat I do the same process of wetsanding,but after the compound I use wax.
Then it will be shiney,protected and smoooooth!

Do not forget to pick up a water resistend sand paper otherwise the abbrassive material will separate from the paper. Wet sanding is also somewhat tricky because you cannot judge a wet surface properly. You have to wipe the water and look at the surface each once and while.

wet sanding is also good in preventing dust particles...especially for resin parts as resin dust is really really bad for your lungs.

The reason you wetsand a paintjob is so that the sandpaper lasts longer. There's really no other reason and it's suggested by some that newbies don't try it until they are comfortable with dry sanding.
The only difference between dry sanding and wet sanding is the wetting agent. For this you would want to add a drop or two of dishwashing liquid (unscented and non-aloe added formula) to a cup of tepid water. The wetting agent allows the particles that are sanded off the surface of the paint to NOT be embedded into the sandpaper's surface and therefore "last longer". An added bonus is that it helps to reduce the friction across the painted surface and reduce gouging somewhat.
Some prefer to do their wetsanding under a running tap using the constant water flow to wash the particles away. I prefer to do mine with a cup under a nice, strong light, using a dry towel to constantly dry the sruface and check my progress.
