I have tried three times to spray the clear coat over a white basecoat, and every time it dries with a grainy, orange peel effect.  Every time I have sanded down to the basecoat, sprayed with the base, and then a few days later sprayed with the clear, with no luck.  I even tried holding the can at varying degrees from the piece I am spraying, still with no luck.  What's going on here? 

Thanks for your time. 

You can get rid of the orange peel by buffing out the part you painted with rubbing compound and a buffer. You can also use 2000 grit sand paper and lightly sand with water. Then buff the finish using a medium cut
rubbing compound.
