I don’t. I spray fairly close to my pad or the panel I’m working on. I also use a different spray nozzle because the one that comes with the bottle is junk IMO. I also try not to polish or compound outside. I have but I try not to. If I just did a full, hard spray then ya it’ll get all over. I try to do a somewhat controlled squeeze when I spray it so it doesn’t look like a blizzard.
