Angelwax H2GO is a glass rain repellent that creates a hydrophobic coating on exterior glass, so rain beads and rolls away at speeds as low as 20mph. It suits windscreens, side windows and other exterior glass, and comes in 100ml, 250ml and 5L. Results depend on preparation: Angelwax advises fully decontaminated, cool and dry glass, an even layer from a microfibre applicator pad, approximately 20 minutes to bond, then a buff with a clean microfibre cloth. A second layer can be added for maximum durability. We pair it with a dedicated glass cleaner, low-lint glass cloths and spare applicator pads, and suggest it to anyone who drives regularly in wet weather.
