I started waterproofing various items when I moved to Ireland. I bought a brand-new raincoat just two days after I arrived here. But after a while, it lost its impermeability. So, I had to look for some smart ways to make my raincoat impermeable again instead of just buying a new one every two or three months. Then I realized that I needed to waterproof everything: my phone, my shoes, my backpack, even my home. Now, I share what I’ve learned about waterproofing and answer your waterproofing related questions.
