I have the Polish Displex bought at the usual use scratch alleviate something in an old Gameboy Color. Overall, it works for the small ordinary scratches, which have been over time on polycarbonate lenses ever (whether Clock or electric), very good. Just repeatedly and longer (10-30min) polish with gentle pressure and Wattpad. You should not be economical, the mistake I had made the first attempt. Especially after meheren passages gets the scratches well out. As some others have written already, longer at lower polishing scratches and repeat several times. This stuff dissolves probably the plastic slightly and thus reduces the edges of the scratches and reduces the (visible) reflections, at the same time be the scratches whether or not filled. At the first crossings no miracles expected.
