Raise your hand if your energy bill was over a gazillion dollars last month. Hopefully I'm the only fool with his hand in the air, but I have a feeling there are others out there like me. Thankfully fellow Hiffer Nick has our backs, as he sent in this free GE Caulk.
I'm no Bob Vila, but I think you can use this stuff to better insulate / seal things like your windows, thus lowering the amount of cold air you pump out to the neighborhood for free. Then again, maybe I'm totally off on this and am about to ruin a few of my windows. Anybody care to leave a comment with some advice?
