Imsure your going to say spray but im not experienced with a sprayer, but I just ordered one. I was thinking of getting the power roller setup to go with it. I would loved to just spray, but im not sure exactly what to do as far as what to spray first, what to tape up, what to cover up, ect.. is there a place I can get some info on exactly how to spray interiors without gettin paint on everything. Of course imgoing to plractice plenty before I go at it!!! Does sprayin cause more prep time than rolling?
