Tools for Paper-Faced Metal Beads
I do mostly smaller jobs these days (basements/additions) so I haven't bought a hopper to put the mud on the bead. It would be worthwhile if you do a lot of new construction. I did buy a roller for outside corners. It helps set the bead squarely on the corner and makes for a better bond. I don't use metal bead for inside corners, so I can't help you with that....
