Glow is hard to do on the blades since it gets thick and can alter the action. Looks like you did a great job though.
To powder paint the bodies on nickel or buffed/polished brass blanks, I cut a two sided "shield" out of thin sheet metal that has the exact contour of the lead body. You can heat and dip the lead body into powder paint and protect the blade from paint. After 10 or 15 you just chip the excess off the shield and keep going. I've been using the same shield for 10 years. (and I make a lot of blades!).
