I pretty much do what you need to do. Mine has an 80 gallon tank, runs up to 175 PSI at 18 CFM. 7 HP 220 volt electric motor. I regulate it down to 100 PSI at the lines and have a good filter/dryer on it. What gets you is a bead blasting cabinet or a small sand blasting unit that uses air constantly. A spray gun if you're painting an old tractor and really pouring the paint on is a big draw too. I don't consider this unit overkill either.
