Wetsanding help

Wet sanding is work and it takes time. Work slow and be patient. Tape off corners and raised edges as you can burn through the paint super fast when wet sanding and ruin all your work. I use sanding pads that go from 3000-12000 grit in a soap and water setting. When you are done sanding you can polish with various types of polish to get that perfect shine. I use Novis polishes for this. Here is a video that should help. 

Here a my Chevelle I did using this method. It looks great after all the wet sanding.

Good luck,

Thank's for the video! I already watched that, but I will watch it again.

It depends on the size of the spots and their distribution.  It was not that evident in your photo.  I think 4000 grit is too fine for normal dust spots.  I usually start with 1000 for normal dust spots, or 600if they are larger or of high density.  Yes, it will be dull when you finish, but that is what polish or very fine sandpaper are for.  I never use finer than 300 myself.  Beyond that I like polish.  Polishing vs sandpaper is a personal choice.  Polishes vary in fineness, though there is not the popular standard like for sandpaper.  Auto body rubbing compound is a fairly agressive grit.  Regular toothpaste is a good medium polish.  There are some wasless auto polishes which are quite fine, but hard to find.  Auto body supply stores may have them.  If you know you have a decent final finish you can you can use a combo wax/polish, but it is very hard to get a good paint job over wax.
