Most of my experience comes from slamming out apartment interiors and it's not as crucial for bleeding issues, they get turned over so many times I don't think smoke damage has a chance to show itself after the paointing... lol. That has been a while. I rarely do an interior and when I do I rarely if at all get any smoke damaged jobs. I have no doubt that the experience you all talk about is true. I'll consider some new steps in my prep if I ever come to this issue. Thanks!
