I've painted several rifles at home with Cerakote using a Preval sprayer and then baked them in my oven. Yes I'm single.
I just ran the self cleaning cycle on the oven afterwards and had my windows open during the baking process. As for the Preval sprayer, just use a few old parts that you don't care about to practice on and determine the right spray speed and distance before you hit the good parts.
