I was thinking of painting my AR with Duracoat and was told that the CeraKote is much more durable. I went to the CeraKote Site and watched a video on ware using a 1,000 pound pressure simulator and revolutions.
Basically, Duracoat could handle 449 rotations before ware failure and CeraKote had over 5,000 before ware failure.
I contacted an applicator I have dealt with in the past for other things, acoating.com, and they gave me the price of $50 for the lower and $50 for the upper, plus shipping and needs stripped down or they can do it for additional cost.
Duracoat seems to be good but for a life time product, I'm going to go with CeraKote.
Also Duracoat would be good for something you plan on changing colors up and aren't worried about ware after a short time, like a daily carry that you just want function, not perrty and perfection.
