2. If you don't have these tools, you can use sandpaper.
3. Once the paint has been removed, you can assess how much rust has affected the metal and decide based on this whether the entire panel needs to be replaced (if possible) or restore the damaged area.
4. New body panels are not as expensive as many people think, and it is often quicker and more cost effective to install a new panel than to try to repair large areas of corrosion.
5. Remove all elements from the damaged area except those that can serve as a template to restore the panel to its original shape (for example, headlights).
6. Then use tin snips or a hacksaw blade to remove the rusted and corroded metal.
7. Fold the edges of the hole inward to create a small indentation for the primer.
8. Clean the affected area with a wire brush to remove rust dust from the rest of the metal surface.
9. Paint the affected area with anti-corrosion paint, if there is access to the back of the rusted area, treat it as well.
10. Before applying the primer, you need to cover the hole somehow. This can be done with aluminum or plastic mesh or with aluminum tape.
11. To cover a large hole, it is best to use aluminum or plastic mesh or fiberglass.
12. Cut a piece of mesh that is roughly the shape and size of the hole, then lay the mesh over the hole so that its edges are below the level of the rest of the plane.
13. The mesh can be glued in place with a few drops of primer applied around the perimeter.
14. Aluminum tape should be used for small or very narrow openings.
15. Unroll the tape, cut a piece to the required length and shape, then remove the protective coating (if it is glued to the tape) and seal the hole; you can stick another layer of tape if the thickness of one layer is not enough.
16. Press the edges of the tape with a screwdriver handle or similar tool to ensure it fits snugly against the metal.
