Can you sand out dust in candy paint

Also, every time you go to a finer grit, clean out your water container carefully and get fresh water. Grit particles from, let's say 2400 pads, that come loose during sanding and get suspended in the water will make SCRATCHES when you're sanding with much finer grits like 12,000.
Also be careful when you start to sand out the trash. If it's a little hard thing, it will also make a SCRATCH when it breaks free and gets slid along the car body. Really pay attention to what you're feeling and hearing when you're doing this.

Any sanding, wet or dry, will alter the thickness of the paint used. On solid colors that won't be a problem, However, alter the thickness of a candy color significantly, the shade of color will be lighter in that area than the surrounding surfaces. It's going to take a pretty delicate, careful touch to wet sand out those specks of dirt.

Candies are extremely difficult to spray and get exactly even coverage anyway. A lot of 1:1 cars have visible stripes in the candy where the build is heavier in some areas, owing to improper overlap of paint gun passes, and there's no way to fix that, but I have sucessfully sanded small dust nibs out of candies. ALL lacquer candies got sanded and buffed back in "the day", and urethane based candies do today.
Whenever you touch a candy color with anything, sandpaper or polish, you risk getting blotches of uneven color. So VERY VERY careful is the rule. Color sanding of a candy color on a crowned panel, the top of a fender for instance, is a scary proposition even without dust in it. But unless you can lay the paint down perfectly slick, which is pretty doubtful in most cases, you're going to have to color-sand anyway to get show-quality paint. Again, because a sanding pad is a "block", it's possible to just kiss the surface and let the bolck shave off the dust nib without going into the surrounding color. Then, colorsand and polish as you would normally.
