I've been waiting for a "blem" set to pop up so I can do similar. I do a lot of custom firearms cerakote work and have a room full of different colors.
Just FYI, 275 for 2 hours makes it more durable than 315 for an hour. I have both heat cure and air cure graphite black so will probably just spray in whatever I'm loading up next. Most likely the heat cure, it holds up better, I don't care what anyone says. I've done many suppressors in the air cure as it has a higher temp rating, and it holds up to full auto suppressor fire decent, but in general scratching doesn't seem to hold up nearly as well.
actually had to set the beer down to hold the tip in place..
