I have been using a roller and brush for years to paint interiors. most of the time it come out good. but i see the pros spraying everything from the wall to the trim. They mask well and it comes out great. many years ago I tried spraying trim in my garage and the overspray was crazy.after that I never tried again. I think it was my inexperience that was the problem. So what has your experience bben with spraying paint on interiors?
