I spritz with water from a fine spray squirt bottle and that revives the styling product used the day before then i add a bit more gel to those wet areas and diffuse those area dry. I do get a tiny bit of frizz but that's ok with me as long as it's not totally frizzy.
Then I've been spraying the mister right on. It's not doing anything bad but I'm not sure it's doing anything at all. But I have a whole bottle of it so I'm using it.
