I do Dura, KG, and Norrells as well as some bluing and parking. You will do fine if you remember a coule of things.
1. The paint needs to be well mixed. before application.
2. Most importantly clean and degrease THOROUGHLY. Even the oils from your skin will ruin the new finish. I wear powder free latex medical gloves when I spray coat.
You don't need to bake it to cure it, but for them to warranty the work it must be allowed to air cure for up to a month. Yes a month. Blasting is best but it can be sanded if necessary. You are just giving the coating a little "traction". Don't use glass beads and don't go too aggresive on the blasting media as you can actully create pits in carbon steel. Blast aluminum at a lower pressure than steel. I do aluminum at 40 psi and steel at 80-100 psi. Acetone works well on cleaning up your airbrush, spills and mistakes.
