Paint Question

I am completely new to body work and paint. My question is what exactly to use. I have to been doing a lot of looking at research. My current plan is to sand, sandblast, and use rust converter inside where it is hard to sand. After that I plan to use PPG DPLF overall. If that looks good I am going to topcoat then clear. My body is currently completely smooth. Just on dent in the rear which will be taken care of. No major rust except passenger floor and truck. All getting patched soon. This is not meant to be a show car. Are there any steps I should add, look into, or change?
