Condition Some vehicles may have the appearance of blistering or bubbling paint on the top of the hood or under the hood edges and hem flanges. Correction Important: Always follow your paint manufacturer's instructions for specific product usage. 1. Remove the hood from the vehicle. 2. Wash the complete hood with soap and water. 3. Wash the hood with wax and grease remover. 4. Inspect the hood for paint blistering (top of the hood and under the hood edges and hem flanges). Important: Because the hood is made of aluminum only, use clean discs so that the aluminum surface of the hood will not become contaminated with foreign particles. 5. Clean blister areas by spot media blast or a 3M(R) Roloc clean and strip disc, P/N 07466, or equivalent. 6. Feather edge and clean. 7. Prime the affected area, seal the complete panel perimeter hem flange using 3M # 08370. 8.
