Hence, it looks like the texture of an orange :)
To kinda piggy back on this...there are a couple of other things that can cause orange peel...1 being oils from your skin coming in contact with the unpainted surface before paint is applied. (However, this can also cause "fish eyes" or where paint repels from a particular spot when applied) Tack cloth residue can cause both, moisture in small amounts,(but moisture usually ends up causing fish eyes). All in all he nailed it down, i just wanted to add a little to that for people who want to know more about paint and body work....
