You are probably gonna get alot of different opinions, as everyone has their preference as what product works best. From my own experience, I find the RAGE (either gold or extreme) brand filler is awesome. Pinhole free, and sands really easy. Are you taking the truck to bare metal or just scuffing the existing paint? That has an effect on what grits to start with, and the tech sheets for whatever primer you are using will give you what grit works best for their product to stick. Just don't use rattle cans, as you will for sure be wasting your time and money.
