WPF Next Gen is the ideal paper abrasive for effective hand sanding both wet and dry on multiple surfaces. It is very flexible, fully waterproof and has great grain adhesion. Produced with new coating technology, the abrasive surface does not clog up easily, so you can sand faster and the abrasive lasts longer. Especially recommended for automotive refinishing due to the consistent surface finish. The finer grits are optimal for fresh clear coats and make polishing easier.
