Hi Walt. The polishing with Nuvite is easy, but it's very dirty. Wear old cloths. Use TSP (Tri-Sodium Phosphate) to clean the polish pads. Start with F9 grit on 6061, and do 3 or 4 passes with it. You'll get the hang of it quickly. Use mineral spirits to clean & wipe. Have several rolls of paper towels on hand before you start.
I wish you the all the best with your project. If you ever get the chance to visit the Zenith factory please take the time to stop by our builder assist facility too. We are their newest and nearest builder assist facility and like to have visitors. We are right here in Mexico, Mo., not far from them as well.
