I will be repainting my kitchen ceiling in the next few weeks. There is a drywall seam where the tape shows- you can see a distinct downwards peak at the seam, and can sort of see the tape itself in some places. The ceiling is slightly textured. I was planning to prime and paint. Is this fixable without a major epic- would be willing to sand and mud the seam/ tape, not going to want to do something major like skim coat the whole ceiling.
