I have been practicing painting for the past week using SEM aerosal paints.  They come out looking decent, but they have orange peel.  I have tried wet sanding with 800-1000-1500 grit papers but the results aren't great.  The peice comes out looking very dull, the orange peel doesn't sand evenly so in some places there is some, other places there isn't and it just isn't working too well.  Spraying a coat of clear would probably help bring the shine back up, but I am not looking for a gloss finish, I want a satin black finish. 

So my question is am I painting or sanding wrong, or is it just not possible to get an orange peel free finish from a spray can?  Any suggestions on what I can try to do differently.  I've read everything about painting I can find on the internet.  I use a sanding block, I've tried a hard one and a soft foam one.  I spray about 12" away from the peice with thin coats and allow about 10min -15min between drying times.

what type of material are you painting? your methods sound right. if you realy want to go crazy with it you can just dust the peice with paint and then after a few minutes do medium coats. that seems to always work for me on plastics and interior trim pieces.
as far as sanding goes it will be dull until you hit it with some compond. you are going for a satin finish so this is realy not an option

when u lightly spray the piece with paint u have more orange peel than if u do a full wetcoat of paint. When u mist it on u are basically creating more spread out high spots with the paint and the orange peel will be worse because of this, if u lay a full wetcoat u minimize the orange peel but if you're not careful u can get runs easier. Both spray cans and spray guns will still cause the paint to be orange peeled to a certain degree u can still get nasty orange peel from a gun from improper settings or mixing the paint wrong (been there) all cars have orange peel as well, some worse than others unless it was professionally painted and care was taken to remove the orange peel via wetsanding. I have removed orange peel from acrylic enamel then polished.Orange peel -- posted image.

Yes, spray thicker coats to minimize orange peel. Practice once or twice to try and get it as thick as possible before you get runs. Of course, a paint gun would work much better, but if rattlecans are all you have, do with what you got.

Spray one coat..... a complete coat. Now, once it begins to flash off (IE: Dry), hit it again only with a decent heavy coat. It will "sit down" a lot better.

after you wet sand you have to buff it out too if you wanna get the shine back.

Use a cut & polish ( 3M makes one ) and it works wonders !!

I second the 3M polish. You won't remove all the orange peel when you wet sand, but it will not be seen after polishing. All your trying to do is remove the overly high points and make then not as noticable.
Why do you ask if I ate paint chips when I was younger?
