has anyone coated their rifle? i am looking at colors, not to give it away, and cerakote and duracoat are the top contenders. now i can prep the gun, but i don't own a sprayer, which i could buy, cerakote sells one on their site for $35, but my compressor is 26 gallon, is that too big for fine detail work? how hard is it to get right? how much do you need? if i have extra i will do one of my glocks, but i just want some first hand info. on a side note, i contacted one of the "certified" cerakote guys in my state, and his response was to send a pic first, so he'll have an idea what i want, because he's unfamiliar with what i asked,(free float rail, matching receiver set <dontknow> ) but he also mentioned recording the serial numbers for the atf….. and i can't figure out why?
