I pulled some corner bead off and there are large patches of surface rust on them. I've decided that rather than mess with Kilz or Rustoleum, I'm going to replace the corner bead with vinyl. If I tried to treat the metal I'm thinking I would probably have to sand down to the metal to get rust off which seems as much or more work as just ripping it out and replacing. I'm thinking I will use adhesive on the new vinyl rather than any nails or screws. Reasonable?
I'm going to start with one room first as a test. All the corner bead is off (as well as baseboards, etc). I have some questions about installing the new corner bead. Before installing do I need to remove (by sanding) the existing paint / compound for a few inches? I'm not sure that if I install the new corner bead whether it will blend with the existing area unless I 'take some off' to give me room to feather. Or do I just feather over the painted surface and build it up? Will all these raised edges be really noticeable?
Suggestions / insights please. Thank you.
