If I read the how to I just found correctly, on rounded corner beads you don't mud over the rounded part of the corner bead, you just texture over it and paint it. Is that correct? Or do I have to find some way of mudding the corner so it looks decent after I've gone around the rounded portion of the corner bead?
I currently have mudded up to the corner so it would be ready for texture if I don't need to mud over the corner it's self.

 

"you don't mud over the rounded part of the corner bead "

That is correct. As the long as the mud on each side of the round corner bead is sanded smooth onto the round edge, it is ready for texture/paint.
