Need help in smoothing

Hello everyone. Sorry for my English. I just started to understand ZBrush. Basically, its not so dificalt, as I thought.
But I faced with problem of the choice of brushes.
Detail - a horns, they are made of metal. In maya I made a simple mesh, but I decided to finish it in ZBrush, because it seemed easier to do here (and so it is). Now they must be sanded, as if it were metal, a smooth surface, but I got it like clay. I tried to smooth it, but it turned out not what I need.
At this stage, I use DynaMesh, because later i need connect them (it will be something like a crown). Then I will use ZRemesher and add some SubDivLevels. I need a sharp edges (I used Pinch & LazyMouse). But how to make a smooth surface? I tried Trim, Polish, but that is not something that I want. Or I must customize them?
Also, the difficulty with the ends of the horns. It is necessary to make them quad, but something went wrong. You can see in the picture. When I smoothed one side comes at each other.
Need advices.

You could try the Trim Dynamic brush, the polish or planar brushes, or possibly try using clay polish. Look up hard surface modeling techniques for ZBrush. There are a ton out there.
