There are a few things you can do to keep the rain off your glasses. First, make sure your glasses fit snugly on your face. If they’re too loose, they’ll slide down when you start to sweat and rain will be able to get in. On the other hand, FAS polymers like Aquapel chemically bond with your glass, allowing them to last an extremely long time. However, the process used to create this bond diminishes its ability to shed water, meaning they don’t work quite as well as PDMS polymers at repelling water. This is why it’s important to invest in a waterproofing agent to help preserve your clothing and gear. In the buying guide below, we’ve shared key features for choosing the best waterproofing spray for outdoor fabrics. In addition, the guide walks you through selecting a spray formulated for your gear. If you’re concerned about changes to an item’s color or texture, spot-testing on a small area is always a good idea. There are a lot of smaller, high-end brands producing windshield water repellents, but only Gtechniq G1seems to have really gotten it right. Gtechniq is a highly respected brand in the car care market that has made its name creating a lot of new nanotech car care products. Gtechniq’s G1 is an ultra long-lasting film that chemically bonds to the car’s windshield, creating a hydrophobic surface that is said to last up to two years. However, anecdotal evidence appears to suggest that its water repellent properties last about one year.

Water isn't the only enemy of fabric. UV rays from the sun can cause discoloration on some fabrics, so that might be a factor to consider when buying a waterproofing spray. And dirt can be an annoyance, too — some sprays can help protect against grime. A wax will require application by hand and then heating (by iron, hairdryer, or campfire) the product to seal it. Waxes are generally only used on canvas, denim, and some cotton materials, so they’re not helpful for most technical gear.Both synthetic and natural waterproofers appear on our list. Many synthetic waterproofers are silicone-based, and non-synthetics contain natural waxes and oils like mink oil or beeswax. Both provide a strong seal against water — Eduard Shimunov of Cobbler Express says silicone-based sprays are like “an umbrella over your shoe,” and Andrade compares mink oil to “a layer of wax on a brand-new car” — and natural products have the added bonus of nourishing the material beneath the surface. (For leather shoes, experts recommend taking the extra step of conditioning them before applying a waterproofer, which facilitates a better watertight seal and preserves the healthiest, best-looking version of your shoe until the next application.) One option is to buy special waterproof cases for your glasses. These are typically made of silicone or another type of durable material and will keep your glasses safe from the elements. You can find these cases online or at some optometry stores. They actually kind of adhere to the individual fibers, like an old-fashioned telephone cord—they wrap around the fibers," says Heidi Allen, the vice president of marketing at Nikwax. "They have a little stretchiness to them." The first thing we noted while applying the product to a pair of leather boots, which is simple with the included cotton terry applicator pad, is how soft and shiny it makes the leather. And there’s no chemical smell; this product can be applied inside since there are no fumes to worry about, and it doesn’t require spraying. After allowing the leather to dry, our tester buffed off any extra protectant left on the surface and let it sit overnight.

lt;li>Durable &ndash; Spray-on treatment restores DWR, resists abrasion and repels water, oil and stains</li> If you wear glasses, then you know that one of the most annoying things is when they fog up. You can’t see and it’s just frustrating. But there’s no need to buy an expensive anti-fog solution – you can make your own at home!But no one likes soaked shoes, purses, or any other type of leather goods, and too much water can eventually damage these items, causing that dreaded drying out or molding. Chamberlain’s Leather Milk Water Protectant No. 3 bills itself as a protectant—creating a water-resistant layer that stops the material from absorbing liquid—and a conditioner. There are many different types of water repellent coatings available for glasses, and the answer to whether or not they are worth it depends on a few factors. First, consider what type of activities you’ll be using your glasses for. If you’re an outdoor enthusiast who spends a lot of time hiking, biking, or running in wet conditions, then a water repellent coating can be very helpful in keeping your vision clear. We found that water rolled right off the treated boots and purse when testing—but do note your item won’t be fully waterproof, as nature intended—and another application is necessary after several uses. When it was eventually sunny enough to apply, the process was straightforward but took the most time here. You’re provided with four applicator pads and really need to apply three layers to get the absolute best protection possible. You then need to apply the G2 Residue Remover (also included) to prevent streaking before leaving the whole thing to set for at least three hours.
