Wall Trim at Rounded intersect
We replaced the old walls with 1x10ís and we use the old metal to secure the old wood frame so we could secure the new boards to it. Now we want to trim the gap that is left. Does anybody know a material that will fill in the gap and look professional? We want it to be paintable. Please include pictures if you have any, I would really appreciate seeing your work and/or hearing your suggestions.
Including a picture so you can see our problem area.
