Stop in for a cup of coffee

Is that for air, not drill? I'd like something better than what I'm using in some of the tight spaces in the rear trunk area. I have flap discs for my 4 and 5 inch Makita's but they take off a little too much material. I also have wire wheels that I use with my drill but they don't take it off that well, I often have to reverse direction to get down to metal. Also have detail triangle sander, good for edges. What do ya think? Mostly removing paint but some areas have a little undercoat if I scraped with screwdriver etc.
Air die grinder with flap wheel,and a 90 degree one with rolock scotchbrite and sanding wheels.
