Painting issues.....

sand it smooth with some 400-800 grit sandpaper. the orange peel is caused by a overly thick coat of paint, so if you lay down thinner coats you wont have this problem. having said that, sometimes no matter how thin you lay the paint on, it still orange peels.

Orange Peel is normally caused by the paint partially drying before it hits the surface of the model. This can usually be avoided by spraying closer to the surface and / or at a lower pressure. If you are using rattle cans you obviously can't adjust the pressure and you have to be careful getting closer to the surafece because of the volume of paint that they put out.

That means you thin not enough you should have more solution. It should be look like the milk from the box. And I not sand I touch with 1500 - 2000 grit with water and after painted let it dry by try to cover it with box or other to avoid dust.
