If you are welding in a patch buy a 4 grinder or a right angle ¼ grinder to grind the welds and cut out the rust. D/A are for large areas of paint prep. Your electric sander should do well enough.
Block sand filler by hand unless you are covering a large area.

I'm gonna try my hand at some rust repair. I bought some 6 inch sanding pads for use with a D/A sander. Question is : Is my electric Porter/Cable Random Orbital sander equivalent to a D/A?? I want to repair & repaint the sides below the lower trim on my el camino. Also Sears has 2 D/A's in stock. Low profile model for $100- believe it said 12000 RPM it uses 7cfm. Or a taller D/A that uses 4.5cfm @ $70 and its 10000RPM. OR ???? if I need a true D/A. Thanx. -- Rick Schaefer 72 TPI El Camino
