How Do You Paint A Car Bare Metal Prep?
If you are repainting a car, it may help to paint over bare metal rather than over a current paint job. This is especially true if you are applying a lighter shade. This will require a lot of preparation, however. You must make sure the car’s surface is completely bare, clean and in good condition to avoid any chance of the new paint peeling off. Make sure you have removed all the original paint from the metal. Sand it away using 320 grit sandpaper or a power sander. Sandblasting can also work as long as you make sure you don’t get sand anywhere inside the car. Clean the entire surface. Use a grease and wax remover solution. Don’t use paint thinner or mineral spirits because they can leave residue. Wipe the surface dry with a tack cloth. Drag the cloth across the surface instead of rubbing to avoid leaving behind any tack-cloth material. Cut away any parts that are excessively rusted or damaged and patch the holes with 18-to-22-gauge metal; this will require a cutting and welding torch
