REPAIR PROCEDURE:
NOTE: When sanding and prep is done you must use clean sanding pads and in a separate room
from ferrous metals, as cross contamination will lead to galvanic corrosion.
1. Remove affected panel. Refer to the detail service procedures available in: DealerCONNECT> Service
Library under: Service Info> 23-Body> Exterior> Removal.
CAUTION! For any panel with exterior mounted hinges, avoid removal of the hinge from the Class-A
panel unless absolutely required. This will minimize the risk of breaking paint around the
hinge perimeter which will create further damage and additional sites for subsequent
corrosion development.
2. 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 ScothBrite Scuffing Disc 07467 Maroon or equivalent.
6. Sand the remaining exterior painted surface of the panel with 800 grit sandpaper.
7. Prepare panel for refinish, remove all remaining dust, clean with PPGT DX330 Wax and Grease
Remover or equivalent and tack cloth the surface.
