Love the sponge from Authentic Premium? This is the solution for you! With the firm sponge to improve grip the other side is cosmetic grade soft to prevent marring on your paintwork as you are waxing! The soft side is dense enough allowing you to spread the wax like butter in the same time does not allow too much product absorb into the sponge! We think everyone will agree with us this is the best value/ quality sponge ever!
