Have you ever shot CeraKote before ? If not, a couple of recommendations;
1. Get a good respirator, don't scrimp on it, it's your health you're protecting.
2. Shoot in a well ventilated area. I didn't used to mind shooting paint. CeraKote is nasty stuff, it changed my mind.
3. Buy the Iwata gun that CeraKote recommends/sells. Don't even attempt to shoot with an airbrush. It won't work.
4. If you aren't going to be doing multiple jobs, it doesn't make economic sense to buy all the parts/pieces to do only one shoot.
5. The usual stuff about prep.......don't Bead Blast. Use Aluminum Oxide @ ~ 80 PSI. Don't cut corners on prep. You'll just flush time/money down the drain and ruin the job.
If you haven't shot CeraKote before, seriously consider sending your parts to a certified applicator. Pay them to do it.
