I bought my cz 75b in august, and already its got little dings and scratches all over it. I haven't been using it rough either. This is my favorite gun that I own, and so far i love everything about it, except the finish seems to be a little subpar. I would like to refinish it before it gets even more dings and stuff on it. What would be the best, and cheapest, way to do this? Duracoat?
