You guys in AZ are fortunate...
I have my FFL to send spoons out for me...cost less than if I did it myself and I don't have to run around. He hates running around to do it, but he still does it. He lives 5 minutes from my house and is very flexible as to when I can stop in.
I skimmed over the RDTS coating and it sounds like a robust system. You'll have to let us know how it turns out and how it holds up...oh dear, that means you have to go do some shooting!
