A good automotive paint job is something that takes either a lot of hard work or a lot of hard-earned money. Whether you painted your car yourself or you had it painted at a paint and body shop, bubbles can appear in the finished paint job. These can be seen when light shines on them or felt when you run your hand over them. But these bubbles don't have to stay there.
Place 1200-grit sandpaper on a sanding block and sand lightly over the small bubbles. Use a water hose in the other hand to continuously run water over the area you are sanding. This keeps the dust from building up under the sandpaper and scratching the car. Sand until the bubbles can no longer be seen, but don't sand through the clear coat and into the paint.
Sand the same area again using the same technique, but this time with 1500-grit sandpaper. This paper smooths the scratches made from the 1200 paper.
Use the 2000-grit sandpaper in the same manner as the above steps. Sand until the entire area is dull from the sandpaper. Rinse the car with the water hose when finished sanding.
Apply the liquid buffing compound to the surface of the orbital buffer and buff the entire car, starting with the sanded area. This fills in the smallest scratches made by the 2000-grit sandpaper and brings out a new shine to the surface of the car. The small bubbles should have disappeared.
