Having done it both ways, I'd say get a small grinder.
I once used a sanding disk in a drill for a big job, removing the (no
longer) antifouling paint from the bottom of a 21 ft sailboat. I am wiser
now. ;)
I recently purchased a Makita 4 1/2 inch grinder. It is currently
one of the more heavily used tools in my shop. The drill is going to be
s-l-o-w. The grinder will take a sanding disk, a wire brush, or a
grinding wheel. As I attack the rust on my '72 Landcruiser, I'm using all
three at differing times. The work goes fast enough to be gratifying.
The one I bought ran $100 or so but it is well worth it.

In a fit of expediency, I merely primed most of my rust spots after
cleaning them. Bad idea. It rained and the rusted almost instantly.
Evidently, primer is porous. :(
Does anybody have any experience with these "rust sealers"?
Permatex markets one as do several other companies. I have some areas that
cannot be ground out, yet have lots of rust. I need something to stabilise
them adequately so we dont rust through again.

Don't blame DRI. They wouldn't approve of this anyway.
