It’s probably old news now but DLC was emerging as a popular choice when I last looked. Also to show I’m open minded, I’ve a few custom ARs in 10+ color cerakotes that hold up fine. Probably because in 4-5 years they I’ve only gotten as far as scoping them a year ago and they are still sitting unfired. I interested in hearing how the Birdsong turns out and any other newer technologies. I’ve a Pre-64 model 70 custom I’m working on that needs a finish at some point. At this rate it’ll be a decade though. Never time anymore for much if anything.
