Mask Surrounding Areas for Spray Painting

got this thing all cocked um sanded spackled now I'm going to uh paint this window and I'm actually going to be using a Gro handheld it's a um I've had one for over 5 years years not a big fan of the sprayer but this is an actual opportunity for me to try it test it um there's not very many times to use a sprayer like that but this might be a time that would work versus hand brushing it so going to give it a try so we're going to mask this window off with paper and plastic and then spray it what
