Anyone have experience with those DIY spray-foam insulation kits (the ones where you get little propane-like bottles)?
Have some "airtight" recessed cans in my attic that are clearly not airtight, so some humid air is coming through & freezing from them. Debating if I blast em with the 'supposedly' vapour re-tarding spray insulation if that might do the trick. Really don't want to go to the hassle of putting vapour barrier boxes overtop of airtight boxes given the # of them....
