Today, Alex and Matt are detailing shoes. Our friends at Asics hooked us up with some amazing-looking and super-comfortable Onitsuka Tigers. Detailing is a physical activity, so it's important to wear comfortable and grippy shoes. The guys always work around water, dirt, and detailing chemicals whenever working on cars, so the time to protect the shoes against these contaminants is when they're fresh out of the box. Shield fabric shoes against stains, spots, and water with Chemical Guys Fabric Guard. Simply mist a coat of Fabric Guard over natural and synthetic cloth, and let dry. Mist 2 - 3 coats to create a durable waterproof shield that helps repel dirt and stains before they can set in. Fabric Guard.
