How to deal with the rust in the car caused by water leakage

Remove the paint from the damaged part with a wire brush or sandpaper, and then decide whether to replace the whole sheet metal part or repair the damaged part according to the damage degree.

Maintenance skills:

If the damage is serious, it is best to replace it in one piece. If the damage is slight, remove the metal loosened by corrosion. Tap the hole edge inward with a hammer to make it slightly concave, thus making it putty. Remove the rust on the metal surface with a wire brush, and then apply a layer of antirust paint to avoid rust again.

(2) Zinc sand is suitable for filling large holes. Cut the zinc sand into roughly the same size and shape as the hole, and then stick it at the hole, with the edge of the sand lower than the surrounding sheet metal part. Then put the filler around the sand, then fill it up and repaint it.

(3) Thin aluminum sheet is suitable for filling small holes. Cut the thin aluminum sheet into the size and shape of the hole, tear off the protective paper, stick it on the hole, stick one or more layers according to the thickness, then press it tightly on the sheet metal part, and finally fill it with filler and spray paint.
