The risk of sanding too deep. It would *very* easy to sand too far with
a ROS without a lot of practice.

That size repair with those black, mesh drywall sheets could be done in
less time than it would take to unwrap the get the ROS out, unwrap the
cord and plug it in. :-)
Seriously, drywall mud is about the fastest thing in the world to sand.


Yep, and one more thing, dry wall dust is not like sanding dust.
It's much more abrasive, and would probaby destroy your sander (not
immediately) but as the dust keeps working at the bearings etc.

I use a dustless system, its a bucket with water, and a hand sander.
The dust gets sucked up by the pad into the bucket of water. A shop
vac is attached... That's the way to go.
I tried using water in the shop vac at first, but the filter clogged. I
found that the special "drywall" bags for the shop vac worked perfectly
(2 bags for about $15).


This system is not water in the shop vac, it's a pre-system before the
vac. Otherwise you'll just fill the filter with the mud.
