Blue Uro-Cell Pads--for heavy paint correction. You will find that using the Blue pad brings out levels of performance of your favorite compound that you have not experienced before. As mentioned earlier, the closed-cell nature of this pad produces rapid surface cutting, producing consistent results quickly. (In fact, some technicians are reporting that with "diminishing compounds", the paint surface is sometimes ready for final waxing or sealing after one step!) Nonetheless, the Blue Uro-Cell pad is great for major paint defect remediation, including scratch reduction and removal of heavy oxidation. And if you find that the paint still needs a bit of shining up, switch to the Orange Uro-Cell pad and your favorite polish.
