Wet & dry sandpaper is a versatile abrasive designed for both wet and dry sanding applications. It features a waterproof backing, allowing it to be used with water or lubricants to reduce clogging, minimise dust, and produce a smoother finish. Commonly made with silicon carbide, wet & dry sandpaper is ideal for fine surface preparation on metal, plastic, and painted surfaces—making it especially useful in automotive refinishing and polishing tasks.
