I have a rubber or plastic backer for my Milwaukee angle grinder and some sand paper discs. From the contractor supply store down the street, I can get the sand paper discs for .10 cents if I buy 10 or more. Any grit. Attaches to the backer with a set type bolt, which holds down the backer and disc. I take the weld down with a regular grinding wheel, and detail with a sander disc. Easy and cheap!!!

I used to work at a place where we used those sanding discs for almost everything. They even bought a cutter that looked like a can opener. You could cut down an old used 6inch disc and turn it into a new 4 inch disc.
I have more questions than answers

For the heavy hogging I use the 4o grit Pro Point 41/2in flap disk from Princess Auto ( The Canadian Harbour Freight ) and the 60 grit Abmast for cleanup if needed. These are both zirconia grit - cut like crazy and wear very well. If I need to fuss up a bit for paint I give a quick touch up with cheapo 120 grit aluminum oxide disks I pick up at the local Dollar store. They wouldn't last long for production work but as metal working is just a hobby for me they do just fine. Have Fun. :P

I have found 9x out of 10 you get exactly what you pay for. A local company has these made with their name on it from a small manufacturer. They are not cheap, but a little less expensive than the big name brands and last just as long if not longer.
I buy their jumbo flap discs in 40 mostly, 80 if I'm polishing up SS.
I will also only buy Carborundum Gold 6" cut off wheels, don't chatter or wander when you start, cut fast, don't chunk, and last all day, and they don't come apart no matter what you do to them. I've seen too many people get hurt from cheap cut off wheels.
