One technique that has been recommended is to grind/clean the rust, tape the underside of the panel to be patched, and then fill the holes with fiberglass resin, then paint and undercoat. This trick is not really a good idea -- when the body flexes, there will be cracks in the fiberglass pieces. | One technique that has been recommended is to grind/clean the rust, tape the underside of the panel to be patched, and then fill the holes with fiberglass resin, then paint and undercoat.

Follow up on metal etches like DuPont's Metal Etch or POR's Metal Ready leaving a phosphoric acid coating on the metal that will prevent flash rusting while storing. | Follow up on metal etches like DuPont's Metal Etch or POR's Metal Ready leaving a phosphoric acid coating on the metal that will prevent flash rusting while storing. | ||
