What we did was, we removed the strips entirely & filled them in with dry wall mud. We also did a thin layer of mud over the whole wall so the paint would stick better (we had that shiny wallpaper crap). My BIL & SIL did the same with their MH. You can't even tell it's a trailer on the inside.krzybo said:You are doing a great job. We live in a mobile home also. Did you caulk around the "wall strips" before painting the room? I want to make them disappear as much as possible.
