Retaping seams on my 12’ high garage ceiling. I am not very good (but getting better!) at this, especially working from a stepladder. I am not going to sand. Will feather it as smooth as I can and call it a day. When I get done it will be light years better than what the builder left. I would normally use BM ceiling paint which I find flat and forgiving and flat white SW Super Paint on the walls. Was wondering if I could use Super Paint on the ceiling too to avoid cutting in. Will the flat Super Paint hide joint compound imperfections almost as well as BM ceiling? Thanks.
