What size and type of tip? And how accurate are you in terms of controlling it? The best way to really know all of your answers is likely to find out by direct observation. Set up a test area, spray some and see.

I just use one strip of 12" paper over the top, and put an extra on top in inside corners. overspray likes to travel up a little more there. I use a 310 or 410 tip.

Of course, I usually spray base before doing the walls...

Water under the bridge, I guess. But mostly that ^^
