Stop in for a cup of coffee

Again, just looking for 'decent' appearance. I was satisfied with the way the metallic looked on the inner stuff. Just would need to get it nice 'from the gun' so no sanding needed.
Does B/C have to be sanded and buffed, or is it 'OK' as sprayed if not looking for high gloss?
base you just put it on, but if you really get to dry spraying it, it can look a little grainy under the clear
