Lake Country's Hydro-Tech Foam Pads are designed to prolong your working time with water-based polishes. Amazing European pre-polymer foam soaks up less product so it stays on the work surface of the pad, where it belongs. Each Hydro-Tech pad can be used with a range of polishes or compounds. Three pads are all you need to accomplish every step of a complete paint makeover. Hydro-Tech foam pads for water-based polishes are available in diameters of 4 inches, 5.5 inches, and 6.5 inches. Use them with your orbital polisher to eliminate paint imperfections and restore a showroom shine. Since Hydro-Tech pads are made for water-based polishes, they are a great choice for professional detail shops.
