Having grown to dislike what the sun does thermally to my black rifles, I've been pondering addressing the issue by getting one or two painted dark earth/tan color. I've seen lots of adds for DuraCoat or Cerakote for firearms, but have no first hand experience. Anyone have any opinions on DuraCoat vs Cerakote when doing AR style firearms? Any opinions on which is better, worse or how it effects the fit and function of them? Lastly, anyone recommend an outfit that does good jobs with them? Something that will last a long time through moderate use? (2500 to 3000 +/- rounds ) a year?
