Remove all trim components necessary to refinish the suspect panel. 3. Wash the suspect panel with soap and water to remove all dirt and debris. 4. Grind the corroded areas of affected panel / component to bare aluminum using a right angle grinder equipped with an 80-grit grinding disc. NOTE: If surface areas are difficult to access with a grinding disc, use a 3” rolocT clean and strip fiber disc attached to a rotary tool to remove. 5. After corrosion removal, feather sand the area with 180 grit sandpaper and finish sand with 3MT Scoth-Brite Scuffing Disc 07467 Maroon or equivalent. 6. Sand the remaining exterior painted surface of the panel with 800 grit sandpaper. 7.
