PSA: don't use spray foam insulation while wearing good pants.

I used the Great Stuff, Windows & Doors version, it's meant to not "overexpand" when you use it in door jambs, etc. Of course, it still sticks wicked well to my clothes!
(my favorite pair of dress slacks, too. don't ask why I even attempted it in these pants, I don't know.)
