The Pontiac was left to cure for a week before Patrick and the Classic Restorations crew began wet-sanding. Using 1,500-grit (600-grit would be the starting point on a two-stage job) on a 3M soft-back flexible sanding block, the high spots were sanded down to the low areas to smooth the paint surface. There should be a uniform dullness of the paint, with no shiny spots visible after wet-sanding and drying, as shiny spots indicate low areas that have yet to be sanded, thus an uneven surface. Next, Patrick and the crew employed 2,000- and finally 3,000-grit to further smooth the surface. It takes about 16 to 20 labor hours to complete this process. Afterward, the Pontiac was washed thoroughly with water. Another week allowed the paint to release solvents after the wet-sanding process, and then the buffing and polishing began. See the sidebar for those details.
