Paint stripping without a D/A

I use scotchbright rolocs for tight areas and good ole fashioned hand sanding. My buddy has a pressure pot blaster he was wanting to sell. I may just buy it for doing the engine compartment. 80 on a DA is just fine for bare metal concidering first layer will be a 2k epoxy. That will get scuffed and a high build blockable primer will go on top of it.
